Well, that's an option. Another thing I would need to get is the Remote
Address. That can be complicated, since sometimes -specially when you are
behind a proxy, or something like that- the IP address you get is not correct.
In those cases with a proxy usually the IP is in a header in the reques
What's wrong with the ideas you've been given? Ying's is exactly what
you asked for, Chris's might be more suitable if you want to set one
or two action properties based on one or two header values.
Another thing to consider is how the values will actually be used: the

I would implement this function as a Utility Class,
and call it from the Action class.
In the Utility Class you can get the HttpServletRequest instance by
[ServletActionContext.getRequest()].
In this case, you even don't need RequestHeaderInterceptor to inject
Headers into your action, because th
Setting the value into the action is both cleaner, and more
expressive, and unless you inject a utility class instance, easier to
test.

Hi Group,
I have a below issue with Data Binding. Consider we have below code
//Model Class
Public Class User {
Private *Date* dateOfBirth;
// Setter and Getter
}
// Action Class
Public Class MyActionClass{
Private *User* user ;
// Setter and Getter
}
In My HTML
Your data is declared as HashMap
So Struts2 don't know what data type the parameter should be converted to.
My suggestion:
Change your Action class likes:
Public Class ActionClass{
private *HashMap* userPropsAsDate;
private *HashMap* userPropsAsInt;
private *HashMap* userPropsAsStr;
// Setter
Hi Li,
Thanks ... Unfortunately, In my case, Map represents various java model
classes at run time ( User, Employee etc ). So I will get the values in a
Single Hash Map ( Using BeanUtils.describe )..
But Yes... as you said, By default struts 2 determine the Object Type using
Type of the attribute
Since you have entities that share *date of birth *, Why don't you
consider using interface power?
You could modify your code in order to manage DOB, by implementing a
simple (f.e.) HumanBeing interface.
public interface HumanBeing{
Date getDateOfBirth();
void setDateOfBirth(Date);
}
}
Then you co
May be you can copy all the properties from a map
to an instance of your model class.
You can implement this by
(1)[BeanUtils.populate]
of Apache Commons BeanUtils
See:
http://commons.apache.org/beanutils/apidocs/org/apache/commons/beanutils/BeanUtils.html#populate%28java.lang.Object,%20java.util.
Hi,
Thanks for the response ... I will try this ...

Gello Dave,
There is nothing wrong with the ideas you gave me. I particulary like
Li's idea. What I'm saying is that to get the IP address is a different story,
since there maybe some logic involved that depends on the context. I'm thinking
which is the most orthodox and clean way to do
Like I said--in my mind it depends on how much of your application
requires this logic. If it covers a lot of the app, I think an
interceptor makes sense. If it's only tiny little bits, I'd inject a
utility class and call it directly.

Hi ... I need to create a URL, like one would get from , but in an
action. Are there any easy ways to do this Struts2, or should I try to fiddle
aroung getting a url from ServletContext?
I am trying to use the tag to allow uploading a file to the
server. However, this tag has to be within a larger overall form.

However, whenever I use the above code, I get the following error when I
click on the 'Upload File' button:
Invalid field value for field "up
It's not legal to nest form tags; that's bogus HTML.
I don't understand what you mean by "the rest of the page doesn't
work"; a file tag is part of a form. You don't submit just part of a
form, you submit all of it. If you're trying to do something like an
Ajax upload, you'd need to do it differen
The first form doesn't contains enctype attribute. Did you try to set
it to multipart/form-data?

Not sure which part of this misson is bothering you.
Basically, you need:
(1)Get the context path of your web app, by invoking
[ServletContext.getContextPath()]
(2)Build the relative path
(3)Build the query parameters what you want
And then combine all of them.
Most time you can implement this b
