Frustrating ClassCastException

I am currently using Tomcat 4.0.1 in a VisualAge 3.5.3 environment with struts 1.0.2. 

Here is the scenario. 

I run both "struts-example" webapp and my "application" webapp, everything works out fine. JSP's and Java files are created in the work directory in Tomcat and everything is hunky dory.

Now I stop Tomcat and bring it backup and then attempt to test the struts-example webapp. It works well. 

Now when I run my web app, I get a ClassCast Exception. Looks like it is caused by ActionForm. But All my ActionForm's blissfully extend 
org.apache.struts.action.ActionForm.

Everything except struts-config and web.xml is the same in both webapps. What could be wrong?

Thanks for your time
