Hi there, is it possible to start a new thread in a different process in Java? I mean, I'm running a specific process and main thread, issuing ProcessBuilder for creating a new process. Before start() method is invoked, one must provide the command to be run in another process. Is it possible to start a new thread in newly created process?
Thank you in advance for the reply.
Best regards.
You need the cooperation of the other process. Some code there must do the actual thread starting. You could pass a command line argument to the new process, or have it make a socket available for a chat so it can ask what to do. The latter option could be implemented using common inter-process techniques such as messaging or HTTP-based web services.
For a simple bootstrap kind of scenario command line args could be enough.
No - that is unless you have the source code of the process you are launching with ProcessBuilder. if you do have the source code, add the new thread there.
