>>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 ;-))

>I've searched for it but could not find it. Can you point me in the right direction? I find it very interesting because I have to call java many times consecutively and I guess it can save me precious time.

Googling "java com integration jacob" turns up on third link when searched with german base URI:
https://sourceforge.net/projects/jacob-project/
which shows 3 recommended ther projects written about in other results.
Misremembered last letter heritage, is Bridge, not Broker, but hinted at keywordlist not returning the entry at all sounds strange.
