ClassNotFoundException error

I am deploying a web application in Eclipse IDE and Jboss 7 . I get this error in server console:

15:32:14,423 WARN [org.jboss.as.ee] (MSC service thread 1-6) JBAS011006: Not installing optional component org.apache.struts2.dispatcher.FilterDispatcher due to exception: java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.FilterDispatcher from [Module "deployment.SampleApp.war:main" from Service Module Loader]
      at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:190) [jboss-modules.jar:1.1.1.GA]
      at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:468) [jboss-modules.jar:1.1.1.GA]
      at org.

relevant web.xml entry:

<filter id="filterdispatcher">
            <filter-name>Struts2</filter-name>
            <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
                  <init-param>
                  <param-name>packages</param-name>
                  <param-value>images</param-value>
            </init-param>
      </filter>

      <filter-mapping>
            <filter-name>Struts2</filter-name>
            <url-pattern>/*</url-pattern>
      </filter-mapping>

I have already verified that web application's WEB-INF/lib folder has struts2-core-2.1.2.jar ...and there is org.apache.struts2.dispatcher.FilterDispatcher present in this jar .

why this error then and how to fix this error ?

Please Make sure you have include six jar for basic Struts 2.0 Application.i think xwork-2.1.1.ja is necccssary .i think FilterDispatcher is deprecated in struts2-core

1 ) struts2-core-2.1.2
2 ) xwork-2.1.1
3 ) freemarker-2.3.12
4 ) ognl-2.6.11
5 ) commons-collections-3.2

Point the above at your WEB-INF/lib directory with parameter FilterDispatcher and tell us what you get

I found the issue ....I had lib folder outside WEB-INF i.e SampleApp/lib

now I cut this lib folder and pasted into SampleApp/WEB-INF/lib ....then eclipse clean build

Now build error has come up in eclipse ...

The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project SampleApp Unknown Java Problem

Cannot find the class file for java.lang.Object.

Make sure you have the jdk set correctly in the build path. Sounds like you might have removed something during your repair
