Returns the exit value of the glassFishProcess. This only makes sense when we ran in verbose mode and waited for the glassFishProcess to exit in the wait() method. Caveat Emptor!

Returns:

the glassFishProcess' exit value if it completed and we waited. Otherwise it returns -1

getProcess

Returns:

The Process object of the launched Server glassFishProcess. you will either get a valid Process object or an Exceptio will be thrown. You are guaranteed not to get a null.

Throws:
