I'm not completely clear on what you are doing. You're are running Weblogic specific stuff inside Tomcat? I don't quite get it. However, the classloading issue is probably caused by a class outside WEB-INF/lib (in a parent classloader) trying to reference javax.ejb.EJBObject. The only way it could do this is to load it via the thread context classloader. Loading it via Class.forName() or getClass().getClassloader().loadClass() won't cut it here. Either your EJB stuff needs to be in the parent classloader so whatever is trying to instantiate it can find it, or you need for the class that is instantiating it to load EJBObject via:
Thread.currentThread().getContextClassLoader().loadClass()
remember that WEB-INF/lib can see the parent classloaders (shared/lib, common/lib, and common/endorsed) but not vice-versa unless you use the thread context classloader. This is a major problem with a lot of libraries out there who use the old Class.forName() which only works within the current classloader and can't even see parent classloaders. There is another version of Class.forName() where you can specify the classloader which you can set as getClass().getClassLoader(), but that still doesn't see child classloaders, only parents.

Within THAT file is the javax/ejb/EJBObject I find that because of the interdependencies of the weblogic stuff and it's use of reflection, you can not have the EJB jars at a different level than everything else. So, all of my relevant jars on in the WEB-INF/lib directory. The only external jar is log4j, which is in shared/lib. So, I'm REALLY curious as to why perhaps my app can not SEE javax/ejb/EJBObject. There is no other javax/ejb/EJBObject that I can find. Any hints would be much appreciated.
