Getting another Java Program's Sound

I'm writing a video recording program, and it's going quite well. I can record mic as well as video from the screen. However, I would also like to be able to obtain sounds from another Java program and then sync them with the video. Basically, record the audio as it is played by the other program.

Is there a way to accomplish this? I'm pretty new with sound, and have read a bit up on it. I think I need to set up a mixer, but I'm not sure if I can actually obtain sound from another Java program that way.

This is not possible with java sound, not because of any particular problem with java sound, but because not all audio APIs that java builds on support this feature. (Core audio on the mac for example, and ASIO on windows. Not sure about ALSA on linux, but I don't think it supports this either).

If you are on windows and want to write JNI/JNA code you can use PortAudio which supports this on one of the audio APIs (sorry I can't recall which one).
