Hello,

Post by Michael McConnell
Environment -
Jini 2.1
Java 1.6.0_03
Eclipse 3.4
WinXP SP2
I am attempting to run the Compute Farm appication using the example
"SquaresJob"
It runs fine if I just use the in-memory SimpleJobRunner, but when I
*java.rmi.ServerException: RemoteException in server thread; nested
java.rmi.UnmarshalException: unmarshalling method/arguments; nested
com.sun.jini.mahalo.TxnMgrProxy$ConstrainableTxnMgrProxy
at
net.jini.jeri.BasicInvocationDispatcher.dispatch(BasicInvocationDispatcher.java:644)
*

Is this the full stack trace?

Which process is issuing this exception? Is it the JavaSpace?

Post by Michael McConnell
Which is completely bizarre because just previous to this the log output
(line 35) stated that it was returning
*com.sun.jini.mahalo.TxnMgrProxy$ConstrainableTxnMgrProxy*.
*

If I had to guess at this stage I would say that some process is
attempting to download the code for the proxy and can't. Which points
to a codebase access problem which could be firewall, messed up codebase
URL, or messed up networking or a configuration problem.

Surely the Germans, who gave us "schadenfreude" and "weltschmertz", have
a term for "the uneasy semi-certainty that one's assertion is soundly
backed by a long-forgotten source." - unknown
A positive attitude may not solve all your problems, but it will annoy
enough people to make it worth the effort.
