En Windows Server con Glassfish 4.0 y JDK 1.7_55 obtengo NoClassDefFoundError y ClassNotFoundException invocando métodos de bean remotos.

StandardWrapperValve[action]: Servlet.service() for servlet action threw exception
java.lang.ClassNotFoundException: com.sun.corba.ee.impl.orb.ORBSingleton

Allí DudgeBean y SolutionRemote son mis clases.
