Jboss 5.1, Struts 2.3.14.2 "Unable to read class..."

Question

I'm writing a new web application with struts 2.3.14.2. Under tomcat 7 it works but under jboss 5.1 struts throws this exception

ERROR Unable to read class [fpf-web.war.WEB-INF.classes.fi.fpf.mvc.controller.IndexController] [ClassFinder.error:38]{main:}
Could not load fpf-web/war/WEB-INF/classes/fi/fpf/mvc/controller/IndexController.class - [unknown location]

here my struts.xml

<struts>
    <constant name="struts.convention.exclude.parentClassLoader" value="true" />
    <constant name="struts.convention.action.fileProtocols" value="jar,vfsfile,vfszip" />

    <constant name="struts.convention.package.locators" value="controller"/>
    <constant name="struts.convention.default.parent.package" value="fpf-default"/>

    <package name="fpf-default" extends="struts-default">
        <result-types>
            <result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" />
        </result-types>
    </package>
</struts>

... my action

package fi.fpf.mvc.controller;

import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.Result;

import fi.fpf.mvc.BaseController;


public class IndexController extends BaseController {

    private static final long serialVersionUID = -2613425890762568273L;


    @Action(value="loadIndex", results={
            @Result(name="indexView", location = "indexView", type="tiles")
    })
    public String loadIndex()
    {
        return "indexView";     
    }

}

and this is my base action

package fi.fpf.mvc;

import com.opensymphony.xwork2.ActionSupport;

public abstract class BaseController extends ActionSupport{

    private static final long serialVersionUID = -4005731572398023270L;

}

Someone knows where is the problem? (I also tried to add

JAVA_OPTS=%JAVA_OPTS% -Djboss.vfs.forceVfsJar=true

to run.conf)

Could you show your web.xml as well? Here you have full example https://github.com/lukaszlenart/struts2-jboss-ear/ — Lukasz Lenart, May 31 '13 at 05:52
I solved the problem by adding this row to struts.xml `` But now a new Exception is thrown as you can see on the post (I edited) on the top. — , Jun 03 '13 at 11:31
I deployed it as an ear and in the eclipse server view, I leave unchecked the option "Deploy as compressed archives". — , Jun 03 '13 at 14:03

Why the downvote ? This seems legit to me.

By the way, the logic suggests that, if the same code runs on an environment and does not run on another one, the problem is in the environment, not in the code.

EDIT

You must ensure that:

your struts.xml file is included in your war;
your struts.xml file is included in the right place;
your classes are compiled with a Java version compatible with the JRE on the application server.

Also check out this answer, and try giving a namespace="/" to your package too

I use jdk 6 to start jboss 5.1. My struts.xml is placed in the right path and I added the namespace as you indicated, but the problem remains... – May 29 '13 at 14:15
