ij to connect the derby still fail. The java process still running and derby can not response normally.I didn't do any special configuration for derby. Just start it using: $DERBY_HOME/bin/startNetworkServer -h localhost -p 1527.
A good place to start is to look in the derby.log file of the Network Server to see if there are any messages there which indicate problems. Another thing you could try is to use 'kill -QUIT' to get a stack trace of the Network Server process. thanks, bryan
