I'm not sure I really understand your question.

If you have some class which invokes loadLibrary then that should just
work.

If you want the loading to happen invisibly (eg, via Class.forName)
then you have to rename your library.

In libgcj, the system classloader looks for classes in shared
libraries.  For a class named `pkg.foo.bar', it will first look for
`pkg-foo-bar.so', then `pkg-foo.so', and finally `pkg.so'.

So for instance suppose you are using the `my.service' package and you
have a class `my.service.Start' with a method `main'.

Then you could make `my-service.so' and invoke:

    gij my.service.Start ... arguments ...

This would magically load my-service.so and invoke Start.main with the
arguments.

Does that answer your question?
