Process Object from Apache Commons Exec

Question

I'm using the Apache Commons Exec jars for creating processes. However I'd like to get control of the process id of processes being invoked.

Is there a way of getting the 'Process' object from the Apache Commons Exec api? I did'nt fine any public methods that returns the 'Process class.

Answer 1

See http://commons.apache.org/exec/apidocs/index.html

Interface CommandLauncher contains several exec methods that return Process.

But anyway you do not have any way to control the process ID: it is the OS responsibility. Moreover standard java API does not allow you even to retrieve the process ID. There was a trick in older java versions: the implementation of Process contained int field pid that could be retrieved using reflection. But this was changed in version 1.6.
