Profiling Java Client apps

I'd like to set some profiling options such as -verbose:gc when I'm  
running in Xcode. I can set arguments for the server side .woa file  
under executables (under Executables), but can't find anywhere to set  
arguments for the client app. Where can I do this?

Does anyone have any other useful pointers to profiling java client  
code?

Thanks
