Help: UnmarshalException running Jini

 Hi,

I'm using Jini for a large scale simulation research and when writing and
taking Entries, I keep bumping into this EOFException error. I'm using
functions with null Transactions which looks like such:
space.write(tripTask, null, Lease.FOREVER);
TaskEntry thistask = (TaskEntry)space.takeIfExists(tmplt_tsk, null,
JavaSpace.NO_WAIT);

Any help would be deeply appreciated!


Thanks,
Samson
