yes, there is no issue with the embedded JRE, it is detected.

What do you mean by the Launcher.jar has no classes? How does it work

Launcher.jar is just a wrapper instead of executing through the command
line. it has only manifest.mf file with Main-Class: classes.myapp and other
options. the classes are in a folder in the same directory.

this is my problem, I'm not able to see other folders in the same
/Contents/Java. it seems the classes are executed as part of the classpath
and not the working directory that it should be in. i will try now with Joe
suggestion to go with the new fx packager, it is certainly the way forward.
