Question

Following thread [entities cannot be cast to javassist.util.proxy.Proxy, i do have now a server side error ( tks thomas) I wasn\'t able to face the real problem within my ap

Answer 1

I encountered the same error and the strange thing is that all the other entities in my project run ok, except one. According to Boris the Spider's suggestion, I checked my project and found that there is a jar called weld-osgi-bundle.jar(in theJava EE 6 Libraries, provided by myEclipse10.0) contains some javassist code which may be conflict with javassist-3.18.1-GA.jarin my web libraries. So I removed it, and the problem gets solved.
