I have a little (I hope) issue trying to use Doubleselect element from Struts2 jQuery plugin and after searching the internet I found nothing about it so I come here to get your help.
I have a jsp with two struts2 jQuery Plugin selects to get the second select (Modelo) loaded based of the item selected from the first one (Fabricante). When the jsp is loaded, the first select is loaded; but when I select an item from this first select, the value of this selected item does not arrive (is value is null) to the action so there is no way to query the values for the second select from database; consequently, second select is never loaded.
I have followed the sample from the struts2-jquery-showcase.
Some info about my app:
struts2 2.3
tiles
Spring 3.1 (I have struts2-spring integration)
Following the code snippets from some files
JSP code for the tiles layout

I am new to struts2. What I am trying is to get data from the client and insert into the db.But while doing this setImageFile(File fie) isnt called and thus imageFile object is null. While other set methods are called and is thus respective members contains values.

sessionMap.put("", name);
}
public String getName() {
return name;
}
public void setName(String name) {

In the above code imageFile is null. And othe members contains value

Use Struts Form tag with enctype attribute.

Below code snippet worked for me

I also configured all the setting for Struts2 basic validation, but nothing is working for me.

My loginAction class is,
package com.test;
import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport {
private static final long serialVersionUID = 1L;
private String userName;
private String password;
public LoginAction() {

public String execute() {

public String getUserName() {

public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
my struts2.xml file is,
<package name="default" namespace="/" extends="struts-default">
<action name="Login" class="com.test.LoginAction" method="execute">
<result name="SUCCESS">login.jsp</result>
<result name="input">login.jsp</result>
</action>
</package>
</struts>
And I place my LoginAction-validation.xml file in the same package where the Action class is placed.
Please lookout my code and help me to resolve the validation issue.
You are returning same login.jsp page in your execute method in action class.
So this results in displaying login page with empty field every time you hit enter.
Try creating an additional jsp to which you are redirected to based on String returned from action class.
other than that i dont see any problem.

But i'm pretty sure there is another option. Just can't seet it.
Thanks for any help.
Solved! It was about scope problem of a form that contains a commandButton. Command buttons (i think..didnt read a formal document about it.) that in a form has a scope of its own form. Cant reach/update/modify elements in an form.
i am trying to work on a drop down list using struts2 tag. But till now i am unsuccessful: below is the .jsp page, the action class, the struts.xml file and all relevant codes. Any help will be greatly appreciated. Thank you.
Note: I am getting this error :-> tag 'select', field 'list': The requested list key 'country' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]

}
}
In this case you are using the Country class as a Map. Simplest solution would be to make a Hashmap property called country with appropriate getter/setters and populate it with what you need.
Then in your JSP you could say something like:
<s:select label="Country" list="country.keys">
or maybe you'd rather
<s:select label="Country" list="country.values">
The workflow should be reverse than above. It should be
action that fills select tag(calls getcountry) -> page with form -> action(to which form will be submitted)
but above we have
page with form -> submitted to action that fills the select, but form has already been displayed.
