Re: Runtime Expressions within Tag


Thanks Wes,

No offense to this approach, but is this the only way to do additions 
(and for this matter, any other operations) within a struts2 tag?. This 
is simply not clean (e.g. adding a property to my action for a counter, 
etc).


Thanks anyway!

Re: Runtime Expressions within Tag


Thanks Wes,

I understood what you meant in your first reply and I appreciate it. 
However I'm used to doing simple calculations on a JSP (like just adding 
a 1 to a guaranteed numeric value), independent of the Action class. I 
guess this is part of my coding techniques in using non-thread safe 
Struts 1.x Action classes vs the thread-safe nature of Struts 2.x (since 
each action is instantiated per request). I must admit I'm still getting 
used to it and their advantages.


I supposed I took advantage of the weak typing occurred in EL 
expressions. My questions was more oriented in whether such weak typing 
can be achieved using Struts 2.x tags. Adding a property to my action 
seemed like too much of an overhead to my action. My first guess would 
be no, since OGNL is meant to encourage strong typing, but thought of 
asking.


In general, I try to keep my JSPs as readable as they can be and adding 
a non-string variable to the JSP by virtue of the Action class didn't 
seem right. Furthermore, it seemed to me like everytime I wanted to do a 
similar computation on the fly, I would need to add a property to my 
action(s) so that i can compute something on a JSP (e.g. looping over a 
collection, etc). But if there is no other way, I'll be adding the 
setter/getter to my Action (I agree with you on the Exception issue).


Thanks for your help!

Since that returns a String, it will be treated like a String. Adding
a getter to your action will pass it through the converters, etc. so
that you can treat it like a number. My second suggestion is to do
some OGNL scripting to convert it, but I would advise to add
getter/setter to your action since a NumberFormatException can be
raised (that could be silently swallowed).

Re: Runtime Expressions within Tag


In case anyone also needs this, I avoided this by using the 
tag (thus using the value stack). It worked just fine without adding the
extra property to the Action class.

development.mode = true


Folks,

When I set the property "development.mode" to "true" I received a lot of 
useful information in case of errors, however i also receive this 
additional Error in my log (when submitting a form):


ERROR ParametersInterceptor [http-8080-Processor24] 11 Dec 2007 
14:20:18: ParametersInterceptor - [setParameters]: Unexpected Exception 
caught setting '__checkbox_dna' on 'class foo.bar.MyAction: Error 
setting expression '__checkbox_dna' with value [Ljava.lang.String;@dc91e2'


Of course this appears for *every* property in my JSP. When I set the 
property "development.mode" to "false", this ERROR log disappears. In 
either case, I properly get my model object updated as I expected (with 
the parameters from the HTML form). IMHO, it seems like the log level in 
the ParametersInterceptor class has the wrong log level but I wanted to 
check if anyone knows anything about this? Am I missing something I 
should be concerned about?


As a way of reference, my action mapping containts:



and my action extends ActionSupport, implements ModelDriven, Preparable 
and ServletRequestAware. The prepare() method instantiates a new 
instance of the model object, so I expect this model to be mapped to the 
properties in the JSP page (using struts 2.x tags) and like I said 
earlier, my model seems to have all needed properties from the request.


Any feedback will be greatly appreciated.

Thanks!

Validation on Struts 2.x


Folks,

I'm not sure if I should be worrying about this, but I'm adding 
validation to our Struts 2.x and we need to decide whether we should use 
Annotations or XML. My first concern would probably be whether 
annotations add (and possibly hurt) performance (this may be if such 
annotations are defined as RUNTIME).


The "annotations" methods seems very elegant, but before on using them, 
I'd like to ask if anyone has experienced anything heavy?


Thanks!

Re: form bean directly into session




I have a form with many, many fields on it.  I would like to process some of 
them in my Action but get all them into the session object so my forwarded jsp 
can use them as the values.  So may I ask:
1.  How can I put the entire form bean from an action into the session scope 
without extracting each name/value pair and individually putting that in the 
session?

Set scope="session" in struts-config mapping.


2.  From the forwarded jsp, how do I access the placed form bean and use the 
getters for the value of input fields?  Thank you.
use struts tags, where the bean name is the name of the form as defined 
in struts-config. Alternatively, you could use JSTL to access these 
forms (beans) as well.

Re: Struts 2 + Spring 2 + JPA + Oracle + Connection Caching/Pooling

Database Connection Pooling is typically handled (already) by the 
container. You can get your datasource from this connection pooling 
using JNDI. Spring has a way of doing this nicely using the 
JndiObjectFactoryBean. Each container has a different way to configure 
this JNDI configuration, so you need to read their documentation and 
play with it.


Now, ORMs typically do their own connection caching (e.g. Hibernate), 
but in my understanding, the prefer way of doing connection pooling is 
via JNDI, so as to use the JEE specification appropriately. In the 
Struts sample, I think TopLink (instead of Hibernate) is used. 
Alternatively, the commons DBCP does connection pooling for you as well 
(if you don't want to use JNDI and rely on the container for pooling). 
It's a matter of creating a new  and let 
Spring inject the one you want.


Your choice, of course.

BTW, this is hardly a Struts question :)

Re: form bean directly into session

However, how do I refer to my placed formBean from a struts tag?  

One way to do it would be:



now "foo" is a variable within your JSP page with the value "fname" from 
your form.


How does it know the difference from my formBean and the default 
formBean created from ApplicationResources?
FormBeans are created on demand according to the mapping of the 
requested resource. This means that if the request mapping was 
"myPath.do" with scope="request", then a new Form will be instantiated, 
otherwise the form will be looked in the HttpSession object. If none is 
there, a new one will be instantiated and placed there as an attribute. 
I guess I never heard of "applicationResources" creating forms (such 
file typically contains resource bundles)


 Can I refer to it as:
 
This should be valid code, however keep in mind that this is only 
because the "myFormBeanName" bean (Form) is in scope (session). If it 
wouldn't, this would have thrown an NPE. I believe the correct 
expression should be:


  

From the documentation 
(http://struts.apache.org/1.x/struts-taglib/tagreference.html#text):


"The attribute name of the bean whose properties are consulted when 
rendering the current value of this input field. If not specified, the 
bean associated with the form tag we are nested within is utilized."


The default value of the  tag is to load the current 
value of the "fname" from the Form object mapped to the surrounding 
. Using it this way (as you wrote will always force to use 
the Form object in session.

Re: substitute for JSP EL tags in struts 2.0.11

If you mean for "jsps using EL tags" the JSTL tags, then a quick fix can 
be to make your EL expressions use scope="request" and make the  
tags (Struts 2.x) use the expression "%{#request.varInScope}" to get to 
them.


If you mean the EL tags from Struts 1.x, then you are going to have to 
change a lot more and take each case indivually to use JSTL (or Struts 
2.x tags). The latter work (in my opinion is more work)

Ok, this is a bit more of a hack, but should work (haven't test it).
From the DisplayTag documentation (note that "id" is similar to "uid"):

"The object representing the current row is also added to the

<% Object job = pageContext("jobResults")

Have you consider whether the using the struts tag there is even needed?
Why not doing trying JSTL with HTML code?




When the checkbox is checked then I should be able to get the corresponding
userid value in the action class. 
Any idea how I can achieve that.

Resource Bundles and token replacement


In struts 1.x, a resource bundle can have:

errors.required={0} is required.

And the validation.xml files will have a param set to the token (key) to 
be plugged in the {0} variable. Is there such a functionality in Struts 2?


I have been able to only print one resource bundle using the key 
attribute in the  tag. The closes I've made it is to 
display the name of the validated field doing:


errors.required=${getText(fieldName}} is required.


If the only alternatively is to write my own template, can someone point 
in the right direction in where, how to get started.


Hope this is not a big question.

Thanks,

Re: [S2]Checkbox value

Yes, you can use tags within tags, but remember that the quotes are 
important:




(Notice the single quotes with double quotes). I see two things wrong:

1. You are calling a method directly. the %{#userId} approach should do 
the trick (so long as it is part of your Action)
2. IMHO, I would almost guess you are missing the tag declaration on 
your JSP page. Have you added <@ taglib uri="/struts-tags" prefix="s"/>



Johannes Geppert wrote:
 type="checkbox" 
value=""/> 


try this version:
type="checkbox" 
value="%{userId()}"/> 


you can't use tags in tags.

Re: Resource Bundles and token replacement


Thanks Wes,

Thanks for your help. The snippet you wrote is valid code, however I was 
hoping for a similar solution where I only need to use the




Normally in Struts 1.x, I'll write  and in my 
validation.xml, I would define the field to validate and the key to add 
to be replaced for the {0} variable. Do you know if this can be done in 
Struts 2.x? I suspect that I can write my own template, but I really 
would hate to do it just for this case.

Re: New to Struts

I agree that it may better *not* to have Struts 1.x background if 
possible, if you plan on doing Struts 1.x in the future (e.g. put it on 
your Resume), please be aware that it is not the same.


If you have a Struts 1.x background, I strongly recommend the InfoQ 
tutorials (there are videos and a three part migration guide).


If you don't know Struts 1.x, then I'll suggest going to roseindia.

Validation error ordering

With the "convention over configuration" approach in Struts 2, is there 
any way to have control over the order of the errors displayed? It looks 
like "conversion errors" are displayed as part of the  tag 
and these are checked before the xxx-validation.xml constraints are checked.


Thoughts?

Re: Required validator dosen't work

You may want to read on 
http://struts.apache.org/2.x/docs/type-conversion.html


The last topic "Type Conversion Error Handling".

I had the same problem. It turns out that there's no "validation" 
concept of a "type" (similar to Struts1"), however Struts 2 will give 
you control over type conversion problems (similar approach, but with 
more control).


So, you really don't have to do much (other than formatting the message 
if the default doesn't suit your needs)

specify range constraints in your validation, or switch to using the

StrutsTypeConverter API

Does anyone knows why the API for the StrutsTypeConverter abstract class 
takes an array of Strings instead of a single one (the convertFromString 
method)? The sample app seems to be always checking for the first 
element. Is OGNL supposed to add more?  Any feedback will be appreciated...

UEL and Struts 2.x

comes with UEL expressions (JSP 2.1 - JSR-245) in using the "#" symbol?


I'm currently using such symbol to get access to "request" attributes 
(so my Struts2 tags can read values from "request scoped" beans), by 
doing the following:


%{#request.myBean}

where "myBean" is an attribute in the request object.

Re: OpenSessionInView with Struts 2.x

2007-12-18 Thread Alberto A. Flores


Thank you everyone for all your input.

I'm currently opting for changing my code (luckily is not that much) to 
never maintained a "persistent" object within the ValueStack, but rather 
a "transient" object. Of course, this is an additional overhead (have to 
copy the object, query, etc, etc), but I think is our best approach 
since Hibernate Validator is not viable option right now (I would also 
argue that validation could/should be pushed back to the model, 
unfortunately we are working with a poorly design db where we use 
reverse engineering to build all hbm and src files and I'm not sure if I 
have enough resources to fix that part of our build, e.g. add Hibernate 
Validator, modify templates, etc).


If I may ask, how to "avoid the transaction commit when validation 
fails" (as you mentioned)?  Is there an interceptor to handle this 
scenario? I see that the workflow interceptor is part of the xwork 
package (not available with Struts2 distribution source code) and before 
I jump into repackaging one from xwork source (which I'm not even sure 
where can I find one), I would probably consider writing one myself to 
handle this case. I also notice that the validate() method is triggered 
before the prepare() method (which makes total sense), however I would 
like to guess that this scenario is best handled by an "interceptor" as 
I sensed such is the recommended approach in the documentation.



Ted Husted wrote:

When a workflow automatically opens and closes a transaction, so that
it can cover multiple operations, and something goes wrong during the
course of the transaction, then we need to rollback the transaction.

In the case of validation, sometimes changes are made to a property
which causes it to become (for example) NULL, and later in the
lifecycle the validator sees that the property is NULL, and raises the
validation error. But, by then, the property is changed, and the
Hibernate Session (or JPA EntityManager) will commit the change when
the transaction is automatically closed.

Since the Hibernate Validator and JSR 299 push validation back to the
model (where it arguably belongs), making it easy to signal for a
rollback in a multioperation transaction becomes more important.

I'm still ramping up on the JPA myself, but in some early tests I
found that not committing the transaction has the same affect of a
rollback.

Re: OpenSessionInView with Struts 2.x

2007-12-19 Thread Alberto A. Flores


Gary,

Thanks a lot for bringing this to my attention. You are correct, that's 
the setup I have in place. I checked my "readonly" configuration and it 
turned out that there was a hidden bug in my xml code (nasty to trace) 
where the "read-only" attribute was not part part of my "get*" keys. I 
changed it and the OSIV started to do the right thing (not persisting 
dirty objects when the view made changes).


Although this is no longer an issue, the problem of the "changed" state 
of the domain object is still reflected in the view (changed properties) 
where roll-backs do no apply on validation errors (the Action method is 
not part of the transaction). Since part of my UI requirements is to 
show the before and after (during the edit process), I really needed to 
have the current state of the object from db. I played with my 
struts.xml to obtain the needed result and was successful with the 
approach of using "transient" objects. A little overhead but it helps 
the purposes of our app (which is pretty extensive).


Thanks everyone for the help given

Alberto

Gary Affonso wrote:

This post is going to make a few assumptions:

1) You're using S2 and Spring
2) You're using Spring's OSIV filter (as opposed to Hibernate's)
3) You're using Spring's Hibernate DAO framework
4) You're using a Spring-configured transaction manager
5) You're declaring transaction boundaries and their configuration 
somehow (declaratively in the xml, for example).


That's a lot of assumptions but that's also the typical setup (in my 
experience, at least) when using S2, Spring, and Hibernate.  If you're 
*not* doing the above ignore the rest of the post.  And ask yourself why 
you're not. :-)


Assuming that's your setup, then I'm a little confused by this thread. 
To get the behavior you describe you actually have to work at it a 
little.  And the implication is that you're getting it by accident.


Here's a snippet from the docs for Spring's OSIV filter:

"NOTE: This filter will by default not flush the Hibernate Session, with 
the flush mode set to FlushMode.NEVER. It assumes to be used in 
combination with service layer transactions that care for the flushing: 
The active transaction manager will temporarily change the flush mode to 
FlushMode.AUTO during a read-write transaction, with the flush mode 
reset to FlushMode.NEVER at the end of each transaction. If you intend 
to use this filter without transactions, consider changing the default 
flush mode (through the "flushMode" property)."


It does this to avoid exactly the problem you're having (objects dirtied 
by the view getting automatically persisted).  Here's a thread about 
this from somebody who wanted to be able to write from within the OSIV 
session but was having trouble doing it:


  http://forum.springframework.org/archive/index.php/t-12414.html

Even though it's pretty much the opposite problem you're having, I think 
it will be educational to give that a read.


Now, you're saying you're getting non-default behavior (your dirty 
objects are being auto-flushed.).  That implies to me that your 
transaction manager is changing the flush-mode of the OSIV session, 
probably because you've used server/dao methods configured as read/write 
instead of read-only.


If that's the case, the recommended solution here would be to see if you 
can easily re-configure the transactions involved with this view.  If 
they're a bunch of hibernate-related calls that are all read-only, just 
be sure that spring's transaction config *knows* that they're read only. 
 That way the OSIV filter will "do the right thing".


Or did I miss something?

I believe the errors are within a "span" with class "errorField" (it may

Re: validation and CSS

2007-12-19 Thread Alberto A. Flores

As the matter of fact, I found several ways in which you can modify the 
outcome of the tag.


The basic (and in my opinion, a hack) is to look at the generated HTML 
code and then use your own CSS to modify the look and feel of your view.
I'm currently using the "simple" theme and in all my "textfield" tags I 
don't see any span associated, but if you do, take a look at the 
generated HTML code and see whether there is any span associated there 
(this is how I figured how to modify the errors generated with the 
.


If you want to get fancy, you can certainly write your own template 
(freemarker). This gives you full support as to how to modify the entire 
HTML code. I would warn you about this one, since it adds additional 
code that unless you are familiar with, you may not want to touch, so 
consider yourself warned :) - This helped me changed some errors to use 
a "div" instead of "ul, li" combination (in the generated HTML code). 
This is done using the "template" and "templateDir" attributes within 
the UI tags. Playing with this can prove very entertaining. I originally 
started by copying the template (ftl template) from the source 
distribution and modifying it so that I can see how things can be done 
(and also to learn some Freemarker).


Note that even if you are not using the *simple* theme, the  is 
meant to give you additional CSS for you. So consider this as you do 
your UI. This is a practice I don't like since personally, I prefer to 
have more control over the produced HTML code, however it's up to you.


Good luck!

Re: Taglib not seen, no text fields?

How are you building your application? It sounds like you are not using 
maven (I highly recommend it so you avoid many problem). Now, a couple 
of things about this post:


- The error you are referring, is it an error in Eclipse or during 
deployment? Two BIG different things.


- If Eclipse doesn't recognize the struts 2 tag, it's because you have 
not included the strut2-*.jar files in the classpath. Please check the 
documentation of Eclipse if you are not familiar how to do that. Since 
the way URI resolution has changed through out the different JSP 
versions, Eclipse will resolve the URI according to the following 
heuristic (see link - 
http://www.eclipse.org/webtools/jst/components/jsp/designs/taglibindex/taglibindex.html)
Please keep in mind that the fact that it resolves in Eclipse is no 
indication that it will resolve during deployment (unless you have a 
good development environment that mimics your deployment jars)


- Depending on the container that you are using, you don't need to use 
web.xml at all (tld file should be within the jar file and the container 
should know where to look for it)


- What jars have you included? At a minimum you shouls have: 
struts-core-x.jar, xwork-x.jar, ognl-x.jar, freemarker-x.jar (x refers 
to the release, which may not be the same). These releases are easy to 
obtain if you use maven. If you don't then, when you download the struts 
2 distribution, these should come. If you are learning, just copy *all* 
and learn what breaks as you take jar by jar off the lib directory.


- If the textfield doesn't show, there may be many reasons for that to 
happen. Have you consider? (i) Not having all jars in the lib directory, 
(ii) your struts tag having a "name" attribute mapping to an unknown 
property. (iii) Have you looked at the produced HTML? (iv) Have you 
checked all logs?

None. I actually use 2.0.11.

And strangely enough, the next example did not show the error, and was

Re: Taglib not seen, no text fields?




No such luck. The error message is gone in Eclipse, but the input boxes and
submit button are still gone in Tomcat. 

you mean the generated HTML code, right?

Strangely enough, the taglib was not in web.xml, but in a jsp. 
uhm? web.xml supports entries for taglibs, the URI in the JSP only says 
look for the tag library definition here (as well as other things e.g. 
namespaces, etc)



So many places to check. As a newbie, I do not know where to check. But
hopefully in the future I will know (as a matter of fact, I already look in
the different log files of Tomcat and Apache, but can't find any interesting
tidbits pointing me to profound knowledge. But that's being a starter, I
think). 
I'm very sorry, but it sounded like you had some experience using 
Tomcat. If not, take a look at the logs directory. Alternatively, if you 
are not familiar with log4j, you could always learn it as well to turn 
on many more logging (or alternatively commons logging). Logging is 
always helpful as you may know by now... :)



On your question of not having all jars in (Tomcats/)the lib directory: No.
Should I copy everything to Tomcat?
No exactly. All jars pertaining to your web app should go in the lib 
directory of WEB-INF/lib directory (WAR file). If you are building an 
EAR, then it should go in the top level (depending on how your 
dependencies are) however I suspect you are dealing with EAR files. 
There are many reasons for this, however such discussion is beyond the 
scope of this thread.



On your second question of my struts tag having an attribute to an unknown
property. I don't know. I think this is not the case, as I use the code of
the author and think this code is flawless (*famous last words of a
newbie*).
I have to admit that I've never used the sample applications to learn 
Struts 2. I've had bad experiences in the past where I find cases where 
things are broken and I don't know if such is the case. But in general, 
a simple HelloWorld sample app should give some light. Not sure what 
your background is (newbie to Struts2 or to all webapp world...) but 
hopefully someone will take a look at it soon (definetely not me) :)



But as I said, the next example is not broken. So I will ponder on. But
thanks for your answer.

No problem! and good luck!

Re: i18n and variable tiles definitions

May I suggest to instead of using the "title" value in the tiles, use

Hi everyone,

I am running into what appears to be a limitation in tiles. I hope someone has encountered this problem before and knows of a workaround.

I have a tiles based layout that accepts a "title" in the tiles definition.

My problem is that I need the title to be more dynamic. It needs to do two
things:

1. Support different titles depending on the locale.
2. Accept a dynamic field identifying the record number that the page is
showing.

For example, rather than say "Record Detail" like in my example it should say "Record Detail:
38847829" and in other languages it should be translated using an existing ResourceBundle (ex.
"Detalle De registro: 38847829").

My problem lies in the fact that my .template tile includes the tag, but does not
know which page it is rendering. Only the "body" tile and the actual tiles
definition knows which page it is rendering for. Other pages use the same .template tile but
require different dynamic fields in their title.

Has anyone got something like this working before?

Re: Struts Token help

Assuming you are referring to Struts 1.x, when you work with tokens the 
servlet will ensure that your response will have a hidden token 
everytime your action finishes execution. It does this so that it knows 
what to expect and control multiple logins. Once it's compared (1 and 
only once), the servlet will get rid of it, so multiple submissions 
(double clicking, back button and submit again) are caught (by 
mismatch). So the behavior you see is the correct one, and yes... you 
need to save it each time (if you want the token checking to work in 
each interaction).


Depending on your application, it may be acceptable to double submit (or 
even use the back button in a shopping cart app) in some parts of your 
application. You typically want to be careful when you are ready to call 
a bean to persist your data, where you need to do the checking. In other 
words, the saveToken prepares your form to be checked for double 
submissions, the isTokenValid() checks that prepared form whether it was 
already submitted.


BTW, unless you have a good reason to use that static boolean within an 
action, this will causing problem. Actions are not thread-safe (they are 
reused during different request/sessions). This is a bomb awaiting to 
explode if you ask me (unless you know what you are doing e.g. 
synchronizing it, etc, etc)

Hi,

Saving the token adds an attribute:

isTokenValid(httpRequest), it is everytime resolving to NULL. 
This piece of code:

some value only the first time.All the other time it returns null. 


Do I need to save the token every time? (Which I dont think so) OR just

I'm resetting the token every time using resetToken(httpRequest).

Re: struts 2 vs struts 1+spring

This sounds like you need to ask this question in the Spring Forum, not 
here. If you don't understand the value of Spring in your current app, 
go ahead and try. Hopefully that will be illustrative. I can assure that 
some of the things you will lose (if you are using at all) are not 
provided in Struts (MVC) and Hibernate (persistence).


If you are following the typical scenario, here are some of the things 
you would lose (that no Struts release will do):


- Transaction Management (if you are using Spring for this)
- AOP support
- Dependency Injection
- JNDI lookups
- Scalable security
- Simple programming model

I'm sure some other people can add more of their own. You must not 
forget that at the end of the day, these are tools. You are welcome to 
write you own version at your own expense :)

Er, huh?

In my experience it's *spring* that sits at the core of an app.  That's
the thing that doesn't go away.

The web-framework (s1, webwork, s2, jsf, wicket), the persistence
technology (hibernate, jpa backed with hibernate, ibatis, etc.) should
all sort of orbit around the spring core, swapping in a new
web-framework should be way easier if you keep your spring core around.

Why would you cut Spring out of the mix when you move to S2?

Re: how to avoid form's validation if the user choose cancel?

2008-01-02 Thread Alberto A. Flores

one way I did that was by using the "non-validating" method point to a 
method (in the Action class) to have the following annotation


@SkipValidation

Then in the struts tag, you force the button to use such method (method 
attribute in tag).


Good luck!

Re: Why should we keep

2008-01-22 Thread Alberto A. Flores

The "driverClassName" uses reflection to load the driver appropriately,
so this sounds like a classloading issue. I'm going to guess that you
are not including the dbcp jar files (you shouldn't be doing this
anyway), thus the Tomcat classloader is always looking for the jdbc
driver in the CATALINA/commons/lib (this is where the DBCP jars are
located by default in Tomcat as per the documentation, see reference).

In general, you want to keep your jdbc drivers maintained by the
container (and not the application). Depending on the type of
architecture you have, you may want to reconsider your need to place
them in WEB-INF/lib to begin with.

Reference:

http://fresh.t-systems-sfr.com/unix/www/apache-tomcat-5.5.25.tar.gz:a/apache-tomcat-5.5.25/webapps/tomcat-docs/class-loader-howto.html

Why should we must place the .jar file in "$CATALINA_HOME/commons/lib" only

in "/WEB-INF/lib" folder??

Re: AW: AW: struts1 and struts2 together

2008-01-30 Thread Alberto A. Flores

I have been migrating code from struts 1.x to 2.x and depending on how 
decoupled your presentation logic is, you should expect significant 
amount of work. The results have been very successful thus far (3 of 4 
modules were migrated completely).


Definitely less code to maintain afterwards and sure it's more readable 
(in my opinion), however the migration is not as trivial and you may 
find some "gotchas" along the way depending on how you have used Struts 
1.x (tags, servlet, dispatchers, etc). Expect a decent learning curve as 
well due to some new features (value stack, thread-safety, OGNL notation)


The one thing I would recommend is to absolutely understand your need to 
migrate. We determined it was the right move based on some of the new 
features that Struts 2 provided out of the box, and we needed for our 
application (We were writing more code just to make Struts 1 look like 
Struts 2 basically).


Hope this help

Re: Actualizar Strust 1 a Strust 2


Para comenzar, necesitas como minimo 4 jars:

* struts-core-xxx.jar
* xwork-xxx.jar
* ognl-xxx.jar
* freemarker-xxx.jar

Si utilizas maven, hacer este cambio seria mas facil. Sino, Ant tambien 
te puede ayudar, pero dependiendo como es que mantienes tus 
dependencias, seria un poco mas complicado. Ten en cuenta que al final 
si se puede mantener ambos Struts juntos.


Todos estos jars tienen que estar en WEB-INF/lib. Una vez ahi, necesitas 
anadir un filtro.  Struts 2 (a diferencia de Struts 1) utiliza 
Tecnologia de Filtros (Struts 1 es basado en Servlets). Esto es una 
ayuda fenomenal pues ayuda mucho al problema de "Thread Safety" (perdon, 
no se como traducir esto al ingles). Si lees ingles, los siguientes 
articulos me ayudaron mucho a comenzar a tener ambos Struts en el mismo 
proyecto:


http://www.infoq.com/articles/converting-struts-2-part1
http://www.infoq.com/articles/migrating-struts-2-part2
http://www.infoq.com/articles/migrating-struts-2-part3

Asi mismo, si tienes preguntas acerca de "Tiles" (si es que lo usas) 
estos tambien pueden usarse juntos. Tiles en Struts 1 es diferent a 
Struts 2, asi que esto tambien debes de considerar al hacer el cambio.


Espero esto te ayude. Buena suerte!

Hi all,

I'm new to Struts 2 (and Struts in general), and I'm having a hard time
figuring out how to handle the simple case of multiple buttons within a
form.  The method I'm trying to use is described in the Struts 2 cookbook
here:  http://struts.apache.org/2.x/docs/html-form-buttons-howto.html.

I've copied these verbatim (along with a small struts.xml to wire them
up), and both button boolean fields always remain false.  Should this
work?  I'm using Struts 2.0.11.  There's always the route of using
Javascript to detect which button was clicked, but I'd rather avoid it if
not necessary.  


I've also seen mention of a Struts LookupDispatcher or MapDispatcher.  Is
there something similar in Struts 2?  


Thanks, any input is greatly appreciated!

Re: Custom Tag Libs

2008-10-08 Thread Alberto A. Flores

I disagree about the difficulty level of writing your tag in Struts2.
However, I would strongly encourage you (as others have) to see if an
already existing tag doesn't fit your needs. I'm hoping to post something in
my blog about some of this soon, however it would be worthwhile to state
what you are trying to accomplish.

Re: migration from struts 1 to 2

d then make sure your own
ActionForms extend ValidatorForm instead of ActionForm. You can declare
validation rules in a validations.xml file. For example, the
validation.xml file you use states that a defect's description is
required. The 'validate' method is invoked by the Action before saving a
record. When the user does not provide a description, the Struts
ActionErrors collection is populated and its contents displayed on the
view page with the help of an  tag.

 “validation.xml” file that validates a form, is described below:

In Struts 2, we define validation in -validation.xml
file. 


For example, validations defined for MyClass-validation.xml are

Re: Injecting Spring Services into Struts 2 Actions

2008-05-08 Thread Alberto A. Flores

Related to this question, I'm leveraging Spring's use of the @Resource 
annotation to the private member variable (no setter needed), thus fully 
relying on Spring's injection mechanism. I supposed it all depends on 
tight coupling to Spring you want to add.


Relph,Brian wrote:

The actions are auto-wired by name by default - so if any of its properties 
match bean-ids in your spring config, and they have setters, then those 
properties will get set.

The part about declaring the dependencies means you disable the auto-wiring, 
and declare your actions as spring beans. So, instead of this:


/WEB-INF/view/index.jsp


You would do this:


/WEB-INF/view/index.jsp


Along with additional spring config:






Notice this does not actually disable auto-wiring (you would have to set the 
auto-wire attribute in the spring config, either globally or per-bean), but it 
does declaratively state what to set on the action as properties.

Subject: Injecting Spring Services into Struts 2 Actions

 
Hello,
 
I found this guide to injecting Spring beans into Struts 2 Actions:
 
http://cwiki.apache.org/WW/spring.html
 
According to the red box at the bottom of the document, the Struts 2 Action does not need to be registered with Spring.  So far so good.
 
However, I'm a little unclear as to how exactly it "knows" what Spring beans to inject into the Struts 2 Action.  Assuming I have a Struts 2 Action that depends on a PersonService, I assume that the Struts 2 Action would have a public mutator for the PersonService like this:
 
public void setPersonService(PersonService service) {

this.personService = service;
}
 
How does the injection system "know" that this method should be used for injecting a Spring bean?  Imagine that the Struts 2 Action has several "set" methods, and that there are a number of configured Spring beans.

It would take way too long for the injection system to look through every "set" 
method on the Action and try to find a matching Spring bean, especially if there are a 
lot of Spring beans (and there usually are).
 
The document above includes this comment:
 
We strongly recommend that you find declarative ways of letting Spring know what to provide for your actions.
 
But it doesn't give an example of how to let Spring know what to provide to the actions.
 
So, the question is:  How do I tell Spring what beans need to be injected into the Action?
 
Thanks

Without even knowing what the exception was there's no way to guess. 
You'd probably be better off trying to diagnose why the exception occurs 
in the first place, rather than ask why it goes away.

Spring Security and Struts2 Using tiles


Folks,

My understanding is that Spring Security does not secure resources on 
*forwards* (I believe tiles2 do forward/chaining). In an application 
using Struts2, Spring and Tiles2, these forwards work just fine. Has 
anyone had success using these three frameworks together using Spring 
Security? I tried it today and It turned out that the security tag 
(http://www.springframework/security/tags/):


  

never fetches anything. Furthermore, the code:

  SecurityContextHolder.getContext().getAuthentication()

returns null (in the forwarded jsp page). Has anyone know what to do in 
this case? I'm beginning to think I can not use Spring Security at all.


Regards,

Re: Spring Security and Struts2 Using tiles

I don't thinks that's possible as the Struts2 result would be something 
like:


my.tile

In here, I don't have access to the forward.

Forwards and includes, that's where I think there may be a fault.
Can you try if, using simple  tags, the security tags work?
