In JBuilder 4.0 under the Tools->Configure Tools we can create a custom command line tool. Can somebody help me as to how to use that tool. If i create a command line tool like

$JDK_PATH
mic -iiop -classpath $CLASSPATH $CLASSNAME

How do i use this command line tool?
Can i run this command tools through JBuilder4.0 ? If yes , can somebody help as to how.
Where do i see the output of the command line tool i.e, where do the errors if any get directed?

I would appreciate any help from anybody as soon as possible.
