RE: Tomcat 5.5.9 with Struts 1.2.7 - ClassCastException - looks like a Tomcat bug
Hi Stewart, I had the same problem and I received a great answer on this mailing list a few days ago. The problem is caused by either one of these libraries that are conflicting with Struts: - jsp-api.jar - jsp-2.0-api.jar On my side, removing these libraries from my project (they were not used) solved the problem.
