Java EE (Java Enterprise Edition) General Discussion

Hello,

I started with what I thought was a working struts application, and I'm trying to use hibernate and spring as well. So I added a large number of external libraries and, without changing anything else (at least, I think I didn't change anything else...), I restarted Tomcat and I get this exception in the tomcat logs:

WARNING: Unable to load config class org.apache.struts2.portlet.interceptor.PortletPreferencesInterceptor at interceptor - jar:file:/opt/apache-tomcat-5.5.23/webapps/portlet/WEB-INF/lib/struts2-core-2.0.6.jar!/struts-portlet-default.xml:17:127 probably due to a missing jar, which might be fine if you never plan to use the portlet-preferences interceptor

The application no longer works. I have struts2-core-2.0.6.jar in my lib directory, and I checked, it does contain the file org/apache/struts2/portlet/interceptor/PortletPreferencesInterceptor.class. Worse yet, I removed the added libraries and tomcat's still giving the same error. I have no idea what the problem is, nor do I know where to look to start fixing it.

Anyone with any ideas?
