I didn't have that problem because I wanted my app to run on Web Start and as a pure standalone app. I had my Web Start configuration set a -jnlp toggle to tell the app what to do.

I also didn't want to sign my app. I used the Web Start classes that only asked for permission when you wanted to access the file system. I used Class.forName() to load my file system system code, driven by the -jnlp toggle. BTW, I love Class.forName(). With judicious coding, it can support all the dynamic loading you need without the nastiness of java.lang.reflect. However, I have an extra reason --- I usually want my code to run on JVMs that don't support java.lang.reflect. I call it "poor man's" reflection.

Of course, this may be more than you want to do to get easier debugging.
