CLONE -ROP tutorial update (seems to still not work)

Tried to set up the tutorial rop client and server. I did it some months ago and everything went ok, but not this time :/

First problem was that jetty returned this error:
HTTP ERROR: 500
Configuration error
RequestURI=/cayenne-service

I fixed this by changing from "Use Options" to "Use a Jetty XML configuration file" in JettyLauncher and point to ...cayenne-tutorial/jetty-run-config.xml. I do not know if this should be fixed in http://cwiki.apache.org/CAYDOC/tutorial-webapp.html or if it will break something else..

Second problem is with hessian. The hessian-3.0.20.jar availiable on http://www.caucho.com/hessian/#Java result in the following error..

java.lang.NoSuchMethodError: com.caucho.hessian.server.HessianSkeleton.invoke(Lcom/caucho/hessian/io/HessianInput;Lcom/caucho/hessian/io/HessianOutput;)V
at org.objectstyle.cayenne.remote.hessian.service._HessianServlet.service(_HessianServlet.java:388)

Switching to hessian-3.0.13.jar fix this problem, but that version is not availiable from caucho any more :/
