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. -----Original Message----- From: hemant [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 03, 2002 10:29 AM To: struts Subject: 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?
