    I earlier mentioned the strange error message I got with 3.0.20

    java.lang.NoSuchMethodError:
    com.caucho.hessian.server.HessianSkeleton.invoke(Lcom/caucho/hessian/

    at
    org.objectstyle.cayenne.remote.hessian.service._HessianServlet.service
    (_HessianServlet.java:388)

    However I did not get a compile error/warning in eclipse. Strange.

    I then removed _HessianServlet and everything seems to work well.

    I have run the junit tests and tested with the Cocoa Client. I do not
    have a java ROP client.

    Hessian 3.0.20 introduce Hessian 2.0 (protocol?). Here are the
    release notes

    http://www.caucho.com/resin-3.0/features/resin-3.0.20.xtp

    "An early draft of Hessian 2.0 protocol is available.
    Hessian 2.0 provides a number of compact bytecodes to reduce the size
    of serialized messages. Hessian 1.0 clients will continue to work
    with Hessian 2.0 servers without modification."
