If you don't mind making the J2ME app non-pure J2ME, you can try the stuff in net.rim.device.api.system, but otherwise I can't think of any IPC mechanism you can use in a J2ME app.

This link briefly looks at a way that this can be accomplished w/o use of the RuntimeStore. It you can use RuntimeStore then go that route, but if that's not an option then this alternative will work (though it's more complicated).
