Thank you Christian - you are correct. A colleague also referred me to: http://www.systemmobile.com/wp/?p=152
I had a copy of jsp-api.jar in my app (/WEB-INF/lib/jsp-api.jar) And Tomcat (both 5.0.28 and 5.5.9) has a copy under $CATALINA_HOME/common/lib/jsp-api.jar This makes the copy in my app redundant and it can safely be removed. By removing it, it resolves the ClassCastException with org.apache.struts.taglib.html.MessagesTei But why should this double presence of jsp-api.jar be a problem for Tomcat 5.5.9 but not for 5.0.28?

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.

Thought you all might like to know.
