The log of the server is rewritten, so I can't find it.
the log of the node as follow:
2011-12-22 16:47:49,404 [INFO ][org.jppf.node.NodeRunner.main(130)]: starting node, uuid=993D2F7EEFE00046EB7ECCAD9BF432A6
2011-12-22 16:47:57,576 [INFO ][org.jppf.server.node.ThreadManager.<init>(71)]: Node running 2 processing threads
the node is on the same network as the server,and this node can cacl the task nomally.
Thanks for your time.
