You already have a couple of answers revolvng around Shellexecute. Depending on your needs you might wish for even tighter integration. Around turn of millenium I was involved in integrating Java routines in a vfp program calling those Java routines directly as biz layer.
We went with a free COM integration packet called JACOB (IIRC JAva Com Object Broker) which worked without problem.

Have read somewhere that a new project was created as follow up, you might still start googling with JACOB java com integration to follow if you need that level of integration.

One of the benefits is it loads the Java runtime coupled to the original vfp process and keeps it loaded for more calls into it: the java startup sequence is only encountered once. Doable with totally separate processes, but would rquire even more unnecessary code ;-))
