MyEclipse 6.0.1M + JSF/Facelets + Tomcat 6

I have been working with the Sandbox MyEclipse Tomcat 6 server and when I tried to deploy to external Tomcat 6.0.16 (from installer) received following error:
javax.servlet.ServletException: java.lang.LinkageError: loader contstraints violated when linking javax/el/ExpressionFactory class ...

There have been some ICEFaces suggestions, but nothing that seems to directly address the MyEclipse WebProject with JSF+Facelets. They point to the el-api/xerces libraries, but that does not seem to correct this problem.

Created simple JSF/Facelets application as baseline and it failed. As did the SimpleFaceletsExample ExampleOnDemand.

It must work since the sandbox Tomcat is 6. Any help would be greatly appreciated.

SandBox Tomcat is a modified version of Tomcat 6. Certain functionality was removed from Tomcat but I guess what your facing is a known issue on Tomcat 6. You can refer to this post for a workaround:-
