    Hello

    I was wondering if someone has tried cayenne with jetty 7 and hessian 4.

    After some trial and error I finally got to the stage where servlet is
    replying, but cayenne fails to establish ClientChannel. this is the log

      org.apache.cayenne.CayenneRuntimeException: [v.3.0.1 Aug 04 2010
    18:38:23] Error establishing remote session. URL -

    seems like something has changed on the deserialisation level(?) in
    hessian, but I cannot pinpoint what.

    Has someone hit or maybe solved this problem?
    Thanks
    Marcin
