I don't think this is the problem, since I understood that there were no needs to install all WebObjects+Project Wonder frameworks because I was taking only needed (Ajax, EOJDBCPrototypes, ERDirectToWeb, ERExtensions, ERJars, ExternalJars, JavaDirectToWeb, JavaDTWGeneration, JavaEOAccess, JavaEOControl, JavaEOProject, JavaFoundation, JavaJDBCAdaptor, JavaWebObjects, JavaWOExtensions, JavaWOJSPServlet and WOOgnl). Now, I was wondering, is there some "precedence constraint" among these frameworks? I know that dynamic class loader, maybe, was intended to bypass these troubles but, I read, somewhere in the source code of application I'm trying to build, to put into Eclipse build path always first ERExtensions then JavaWOExtensions.
