Frustrating ClassCastException

2002-04-03 Thread hemant


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

Take a look at your jar files, specifically for struts.jar. Make sure it is
only available in yourApp/WEB-INF/lib directory and not in you
JDK_PATH/jre/lib/ext or TOMCAT_ROOT/lib or TOMCAT_ROOT/commons/lib.

Mark.
