Hi All,
I am using JBoss 4.0 and struts1.0.
My ear is getting deployed properly but when I give the following url
http://localhost:8080/userLogin.jsp
it gives me the following error

Doesn't struts 1.0 work with Tomcat 5.0.28 version.
What shud I do to remove this error.
I have to use JBoss 4.0 and Struts 1.0 only.
Any help would be appreciated ..
Thanks.....

Looks like a classloader problem. Its not able to find struts classes. I had fixed this problem by specifying classloader at ear level like this in jboss-app.xml file while forming ear file.

<jboss-app>
<loader-repository>EWSEAR:loader=EARfile.ear</loader-repository>
</jboss-app>

Thanks Damanjit,
I was using an old Struts.jar file which was causing the problem.
Thanks for replying.I have fixed the problem but there is another problem which I am facing which I have posted.

Bye
