ClassNotFoundException in Web Application using struts

Question

I am developing a web application using Apache Struts, to be deployed on JBoss Server. Using eclipse for development.

I have configured web.xml to forward all *.do requests to ActionServlet.

A JSP page (abc.jsp) has a form with action="newgoal.do".

The struts-config.xml file has the following entry:

 <action path="/newgoal" type="com.misys.trng.AddingNewGoalAction">
 </action>

I have verified that the path of the class is correct.

All other .do forwards in my web application are working perfectly fine. When I submit the form from abc.jsp, I get the following exception:

2:13:43,793 ERROR [RequestProcessor] No action instance for path /newgoal could be created

I cannot fathom what the error could be. Why isn't my application able to load 1 particular class, when all others are working fine. Please help.

Does the class exists under the WEB-INF/classes on your JBoss installation? — Chakra

It does not, but neither do all the other classes that are loading/instantiating without any issues. — Shailesh Tainwala

The class must exist under WEB-INF/classes or be inside a .jar file under WEB-INF/lib. Make sure it does.

The other Action classes, which are all working fine, are not present in WEB-INF/classes or as part of a jar in WEB-INF/lib. So I don't understand how that alone could be the problem.

The .java files are in a folder 'Java resources: src'. The META-INF folder has a single folder 'MANIFEST.MF'. The WEB-INF/lib folder is empty. And my application is working fine for the most part. What am I missing here?

Perhaps something is static in your action? I had the same problem. One static variable was initialized with a value in properties that did not exist, then the action not is initialized.
