If I understand your question correct, you have a launch4j executable and a native library within your installation directory:

/launch.exe
/bin/lib.dll
/lib/app.jar

Now you want to start you app.jar with the generated launcher (launch.exe). You app loads the lib.dll.

You can embed a file into your app.jar (marker.txt). Now you can use the ClassLoader

getResource("marker.txt);

This will give you something like:

file://c://installdir/lib/app.jar!marker.txt

This String can be parsed. But in fact, I think there should be a better solution for this problem.
