EJB programming & troubleshooting: java.rmi.UnmarshalException: Invalid method hash

  1. java.rmi.UnmarshalException: Invalid method hash (2 messages)

    When I attempt to use value objects to communicate with EJBs from the client tier, I get the message java.rmi.UnmarshalException: Invalid method: hash. I made sure I override equals and hashCode in my code. Do you know what could be the problem.

    Thanks in advance
  2. your client Class nonmarsh your server Class
  3. It could possibly be that your value object is either not seralizable or perhaps something within it isn't
