This is my struts config file:
The root of my project is StrutsProject.

I am trying to access the following URL:

I am getting the following error:

Please help,

Is your JSP file location is correct??
/pages/login.jsp
Or It should be
/WEB-INF/pages/login.jsp

Looks like the Spring listener was not configured for your web app!
Nothing will work until WebApplicationContextUtils returns a valid ApplicationContext.
You might need to add the following to web.xml:
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

How can it be resolved without configuring Spring?
I was trying to write a simple Struts 2 program.
In the struts.xml I am getting the error
The file cannot be validated as there was a connection problem.
My struts.xml is
<?xml version="1.0" encoding="UTF-8"?>

You forgot the <package> element, and DTD should be 2.3:

Yet another question on this I know, but let me just say I looked everything else or about. So, I'm currently building the structure of my Struts 2 Project. I use Struts 2.3.4, JBoss 7.1 and Eclipse Indigo. I also included all the necessary jar into my project. The problem is when I run my application (Add project to Jboss, Run On Server) and go "http://localhost:8080/booxstore/" I get this:
Etat HTTP 404 - There is no Action mapped for namespace [/] and action name [] associated with context path [/booxstore]

<!DOCTYPE struts PUBLIC

<action name="afficher" class="com.booxstore.controller.DisplayAction" >
<result name="SUCCESS">/center.jsp</result>
</action>
</package>
</struts>
My action :
/**
*
*/
package com.booxstore.controller;
import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionSupport;
public class DisplayAction extends ActionSupport {
/**

private static final long serialVersionUID = 8199854978749642334L;
public String execute() throws Exception{
System.out.println("IN");
return Action.SUCCESS;
}
}
My JSP just have plain text and have imported struts 2 tags. Basically no matter what I do I can't get a resource. If I go to "http://localhost:8080/booxstore/" or "http://localhost:8080/booxstore/DisplayAction" I get "There is no action mapped" and if I tried to access directly the jsp I get a 404. Please note my war is deployed and enabled on the server.
Put index.jsp under WebContent folder, move pages folder to WEB-INF and then change the struts.xml with:
<struts>
<constant name="struts.devMode" value="false" />
<package name="pages" extends="struts-default">
<action name="afficher" class="com.booxstore.controller.DisplayAction" >
<result name="SUCCESS">/WEB-INF/pages/center.jsp</result>
</action>
</package>
</struts>
I think that the problem is that the application is not finding the jsps that you are putting in the configuration files. And META-INF folder is not the place for putting your jsps pages if you don't want to make them public, WEB-INF is better for that purpose.
To prevent misunderstandings about mappings, add the config browser plugin jar to your application. It will allow you to browse all pages. Caution! Only deploy the dependency in dev or testing, never ond production. Use maven profiles for this restrictions.

i am absolute beginner to Struts2. I am tying to follow tutorials on struts web site. i followed this tutorial. i have some trouble with it. i created dynamic web project on eclipse. Then i followed the tutorial. However when i run the example i get the following error.
There is no Action mapped for namespace [/] and action name [hello] associated with context path [/Hello_World_Struts_2]. - [unknown location]
i have the following directory structure
And my struts.xml file is
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

</action>
<action name="hello" class="org.apache.struts.helloworld.action.HelloWorldAction" method="execute">
<result name="SUCCESS">/HelloWorld.jsp</result>
</action>
</package>
</struts>
thanks for your responses.
The struts.xml configuration file needs to be on the classpath (as opposed to in WEB-INF).
The linked tutorial assumes a Maven build and states the struts.xml file should go in src/main/resources, which will be included in the classpath in Maven builds. Since you're ignoring that part, you'll likely want to put it in the root of your source directory.
You have to create a classes/ folder under WEB-INF/ and put in your struts.xml file!
Right click the project. Go to properties deployment build path and add all .jar files to /WEB-INF/lib. Then you shouldn't get this error.
struts.xml should be located under directory: src/struts.xml..
And WEB-INF/web.xml you we need to configure the struts based on filter..
I got the same error and got solution looking at tomcat log when restarting : doctype were missing in struts.xml
so I added
<xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
now it works !
I solved the issue by adding default-action-ref tag, for example,
<default-action-ref name="home" />
after package tag
in struts.xml
<package name="user" namespace="/" extends="struts-default">
<default-action-ref name="upload" />
I had the same issue and I was facing it because of not mentioning the namespace correctly in struts.xml.
I added the following snippet in the web.xml :
<welcome-file>login.jsp</welcome-file>
and also making the namespace as "/" default...
Hope it answers your query..
In my case I had to rename Struts.xml ---> struts.xml
I'm trying to get my Struts2 project running with Tiles and REST Plugin but I just can't get it working.
I've looked at the documentation for both and I think i'm doing it right. here are my files:

I'm sure i'm doing something really stupid but I can't see it myself. Anyone?
First, I would suggest putting your struts actions in a package simply called struts, I've had much less configuration issues when using standard conventions plugin architecture. Move your actions to a package like:
uk.co.ratedpeople.struts
instead of
uk.co.ratedpeople.tp;
The less out of the box configuration, the better off you typically are.
This also eliminates the need for this:
<constant name="struts.convention.package.locators" value="tp"/>
Second, part of your problem is with your xml configuration:
<struts>
<constant name="struts.devMode" value="true" />
<!-- RESTful plugin setup -->
<constant name="struts.mapper.class" value="rest" />
<constant name="struts.convention.action.suffix" value="Controller"/>
<constant name="struts.convention.action.mapAllMatches" value="true"/>
<constant name="struts.convention.default.parent.package" value="rest-default"/>
<constant name="struts.convention.package.locators" value="tp"/>
<package name="tradesman" namespace="/beta/tradesman" extends="default">
<result-types>
<result-type name="json" class="org.apache.struts2.json.JSONResult"/>
<result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" />
</result-types>
<interceptors>
<interceptor name="json" class="org.apache.struts2.json.JSONInterceptor"/>
</interceptors>
</package>
Try something like this instead (providing you moved your actions as previously suggested):
<struts>
<constant name="struts.devMode" value="true" />
<!-- RESTful plugin setup -->
<constant name="struts.mapper.class" value="rest" />
<constant name="struts.convention.action.suffix" value="Controller"/>
<constant name="struts.convention.action.mapAllMatches" value="true"/>
<constant name="struts.convention.default.parent.package" value="tradesman"/>
<package name="tradesman" namespace="/beta/tradesman" extends="rest-default">
<result-types>
<result-type name="json" class="org.apache.struts2.json.JSONResult"/>
<result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" />
</result-types>
</package>
</struts>
Notice the constant name="struts.convention.default.parent.package" value="tradesman" which is referring to the package below it which defines your result types and extends rest-default. This should eliminate your tiles result definition errors.
I've also run into issues using the struts filter you have in your web.xml, I would change from:
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
to:
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
