JNI and native exe output

Yes. But that has nothing to do with Java nor even JNI.

And it is certainly easier to just use one of the exec() methods.

I really doubt your problem is not resolvable. I really do. And I don't see how the bug report applies to you either.

Anyway.

The output of the process will be sent to System.out So you'll have to redirect that somewhere back in. You can do this inside your program.

Your C process is the Java process.

Now I think you are saying you are launching Java-> C -> other exe

If this is the case then you need to direct the other exe out though C to standard out.

This seems quite the mess.

Which has nothing to do with java itself.

But regardless, FIRST you must collect the stream output in the C code via some method.

Note doing that is a C problem not a java problem.

So are you doing that? Until you are it is pointless to discuss what needs to be done in java.
