Unable to locate a valid EngineConfigurationFactory

["SINGLETON, SHIRLEY " <sh...@fccj.edu>]

I'm getting the following error working on a uPortal project using Tomcat 5 when trying to load a portlet. This is a runtime error and everything seems to compile fine. I am new to this project and I see that the axis libraries have been placed several different places for class loading. Could that be a problem.
 
Thanks in advance
