Thanks a lot for the quick reply!
As a workaround, I did copy the xxx.clp over to the remote machine.
However I want to make a generic remote worker who just takes a task from
JavaSpace and execute task.execute(). My task is like:
class task{
...
public Object execute(){
...
engine.batch("xxx.clp");
if (engine.run() > 1) { does something and return}
}
}
Yes, I can read the xxx.clp into a string as a part of the task object which
will be serialized to the remote host by RMI. After reading Jesp API and JIA
book, I still could not figure out the Jesp syntax to do what I want to do.
Can you please elaborate more?
Thanks a lot,
Andrew
