Java Question

Hello,

I was wondering if someone could tell me or direct me to a source about how to make programs run in the background in Java.

Thank you,
Evan

In the background of Windows? I don't even know if you can. The java virtual machine would have to be running, which you don't have control over. It runs in the foreground, so it pretty much ruins your chances of having your application run in the background. At least that's what I think.

Do you mean in the background as in system service or as in no user interface?

The javaw command is identical to java, except that with javaw there is no associated console window. Use javaw when you don't want a command prompt window to appear. The javaw launcher will, however, display a dialog box with error information if a launch fails for some reason.

I am not completely sure what you're asking. If you asking about multitasking within your java program, then you want to readup on Threads. You can setup a background thread on a timer tick, for example, to services resources or read a port of some sort. If your talking about a windows service application that runs in the background like a Unix daemon, then you will have to readup on windows services (I imagine there is an API you need to access). I much more knowledgeable about Unix application programming.
