Broadly, you don't. If your application is bundled, it's set up to be
run by double-clicking, and double-clicking has no provision for
command arguments. There is a way to pass a *fixed* set of arguments,
using the Info.plist file[1], but I believe that
it's specific to Java 1.4. If you want something that works for any
version of Java, you're probably better off providing a separate
Mac-specific main() which supplies whatever you need as "arguments".
If what you're asking is how to run your bundled application from the
command line, passing it *non-fixed* arguments, then you specify the
executable file directly:
% ./MyApp.app/Contents/MacOS/MyApp -foo

Because "open" runs an application the same way double-clicking does,
and double-clicking doesn't support arguments.
Overall, it appears you're under the misbelief that OS X runs Java
applications the same way Windows does: by simulating the command
line. It doesn't. The command line in OS X is simply one of several
ways by which programs can be run.
