RE: The design of bread crumb trail
I hope I am interpreting your question properly. If not, sorry. It
sounds like you are asking when you return to page 1 from page 2 should
you re-populate the page 1 form. The answer is usually yes. Either
Struts-1 or Struts-2 tags will help in the re-population. If you want
to use plain html tags with refresh, you can use the jsp EL to
repopulate, something like **input type="text" name="userName"
value="${userName}"** If 'userName' is found in the
jsp-accessible scope, the box will be re-populated.
Probably you should not re-populate sensitive fields like SSN or
password, however.

Thanks for the answers, but I would like a direct answer to my questions
(1)... (2)... . Any thoughts?

Hiding/encrypting URL parameters in Struts application
Hi Is there a way to hide/encrypt URL parameters using Struts? Right now i am passing some critical params in the URL For e.g http://localhost:8080/method=xyz?param1=123¶m2=xyz I want to avoid this. Please let me know if anything can be done about this. Thanks Sid
How to set attribute of
I read document from struts2 and I know has label,name,cssStyle,cssClass,so I use as follows: I want to set label "Your First Name" as red color and font size is 6,but when I execute above code,I found label "Your First Name" is still black color and not red color and its size is not 6,why? How to define label attribute in to realize above function? My other question is when execute ,it will shows follows: Your First Name:|Mary| I want to know how to set its length,such as label "Your First Name" occupy 30% width of line and "Mary" occupy 70% width of line? Thanks

You'll have to do it yourself or use an existing tool to protect these parameters. When I do this type of thing, I symmetrically encrypt the data and then pass the encrypted string as a GET parameter. In order to reduce the threat of replay attacks, I encrypt the expiration date and time of the data along with it and refuse to accept it on the other end if it has expired. There's a project out there called HDIV that is supposed to protect data like this. I don't know a thing about it except that someone posts updates to the project on this list occasionally.

Re: Custom component - custom tag
Thank you:
This looks close to what I need. But I think I am missing something
here. I am setting an abject value in the Action. Where is this object
stored, on the ValueStack ? Basically I am setting a resuletSet in the
action and I need a tag to display it, so How can I access it from the tag.
I tried this:
ActionContext a = ActionContext.getContext();
Object value = a.getValueStack().findValue("results");
but it's not working.

Re: moving on to Hibernate with S2...
If you like RoR (and I do) you might like some of the "magic" that
Struts 2 and Spring can provide. It isn't quite perfect yet (at least
not the Struts 2 part), but I'm pretty happy with it. By "magic" I
mean convention based configuration, which cuts down on the number of
places you have to enter the same data.
With a default Struts 2 + Spring IOC setup, adding a new Action means :
1. Create an Action class
2. Create a view file (JSP in my case)
3. Describe the Action class and view in the struts configuration
file (struts.xml)
4. Describe the Action class in the Spring IOC configuration file
(applicationContext.xml)
5. "Wire" the dependencies needed by the Action class in the Spring
IOC configuration file (applicationContext.xml)
This seems like a lot of work, especially compared with RoR. My
solution has been to use the following pieces of "Magic":
1. Struts 2 "Zero-Configuration"
2. Spring IOC "autowire by-name"
3. Struts 2 Spring Integration
This cuts the above steps down to:
1. Create the Action class.
2. Create the View file
3. Annotate the Action class.
4. Add IOC properties to the action class
This only saves 1 step, but it cuts the number of configuration files
edited from two to zero. In fact, the only files that need to be
edited are your Action and your View, which is just what RoR requires.
The downside, is the mess of Annotations that this approach requires
on the Action class. There is also a "codebehind" plugin for Struts
2 that I have yet to try out, but might cut down on the required
Annotations.
The missing piece here is the Model component. Hibernate offers one
solution, and by using Annotations instead of mapping files, you can
get close to the simplicity of Active Record, though not in terms of
setup. My preferred solution, as of late, is to implement a Data
Access Layer. This is more complicated, and more work to setup and
maintain than Active Record, and certainly requires more typing than
Hibernate alone. However, I find that more often than not, the
database can prove to be a performance sticking point. By having a
clear DAO layer I can tweak resource hogging auto-generated queries
without having to touch domain logic, which is what I found myself
doing when relying on Hibernate alone.
For example, if I have a survey building tool with an administrative
front end, and I have an Action defined to assign questions for a new
survey, the action might receive a surveyId and a list of questionIds.
With Hibernate alone, I would be tempted to write something like the
following in my Action class:
Survey selectedSurvey = new Survey(surveyId);
hibernateSession.load(selectedSurvey);
selectedSurvey.setQuestions(null);
for (long questionId : questionIds) {
Question q = new Question(questionId);
hibernateSession.load(q);
selectedSurvey.addQuestion(q);
}
hibernateSession.update(selectedSurvey);
Now, that's a terrible example of database usage, but it sure was easy
to write, and its rather readable, even with no comments.
Now, with a DAO layer defined, I might write something like this in my
Action class:
surveyDAO.setAssignedQuestions(surveyId, questionIds);
In the definition of the surveyDAO, I might use the same code that I
previously put in my Action class, and it might never prove to be a
problem even with all the excessive database. However, if it did
prove to be a problem, I would know exactly where to address it, and I
could be assured that my database performance tuning would be
restricted to its own layer, and would not make my action any less
readable.

Personally, I do *NOT* like to use Spring, because every time I touch it
everything breaks. I think that a better solution is to use a
ServiceLocator to provide the Hibernate SessionFactory. I did this in S1,
and it worked very easily, and didn't break anything. ServiceLocator is
described in the "Core J2EE Patterns" book very nicely (available on-line at
Sun). In my opinion the rush to IOC and DependencyInjection is more of a
fad/hype than a real benefit. ServiceLocator is easier, and makes your app
more portable, because you don't have to implement the IOC service before
you can get your code to work in the new framework.
All this, of course, is IMHO, and I know I'm probably a minority here.

datetimepicker support for time zone and locale?
Does the datetimepicker have support for specifying different locales and timezones? I am presuming that it takes into account the locale specified by the request, but don't see that specifically mentioned anywhere.

Problem with text encoding..
Hi, I am using Kubuntu edgy OS.. I installed Netbeans yesterday... The installation went smooth and fine... here are the setup I have, 1) JDK - 1.5.0_11 2) Netbeans - netbeans-5.5 3) Tomcat - Bundled with Netbeans... I thought of developing a Struts application in my Language - Tamil... so followed the instructions in http://www.netbeans.org/kb/50/quickstart-webapps-struts.html replaced the text/strings in .jsp pages to my language... also replaced the text/ string in ApplicationResource.properties file to my language... Problem #1: In Netbeans IDE the text display wasn't proper.. both in .jsp and ApplicationResource.properties files.. in .jsp it was squares... and in ApplicationResource.properties i had some junk values... so used Kate text editor to edit the .jsp file and ApplicationResource.properties files... after completing i gave F6 and ran it.. it was successful.. The firefox browser opened... and the action was called.. Problem #2: but the Tamil text that I had given in the .jsp file was properly displayed... The text that i gave in ApplicationResource.properties file wasn't displayed correctly... I have uploaded the screenshot in the link given below The junk values can be identified as those next to "Your Name" in English.. http://flickr.com/photos/[EMAIL PROTECTED]/495583036/ Kindly help me in fixing Problem #1 & #2..
