KOMBALA VITHANAGE INDIKA KUMARA commented on DERBY-5261:
--------------------------------------------------------

I don't know how to run "java -jar derbynet.jar abc" in method, can any one
send me example method to test user commands for "derbynet.jar".

> If you invoke NetworkServerControl with an invalid command, the usage message will be printed twice.
> $ java -jar derbynet.jar abc

> Printing it once should be enough.
> The same problem is seen if you don't specify a required argument for an option. For example "java -jar derbynet start -p" (no port number).
