Question

I am trying to start a new process using Runtime.exec(), but my problem lies within using ssh to remote in and then run a java program there. Code:

test = "ssh -t username@host java packageName.ClassName portNumber (Other command line args for this class)"
Process proc = Runtime.getRuntime().exec(new String[] {"/bin/bash", "-c", test});

this doesn’t fail or catch, but I need to be able to see the stdout for the newly running process and I don’t.

Note: if I run ssh -t username@host java packageName.ClassName portNumber (Other command line args for this class) from the command line it works fine. I have the host setup to not require a password by using ssh keys.

Any ideas?

You need to use Process.getInputStream to obtain the output from the sub-process being created.

See this article for a good discussion on Runtime.exec.
