Comment posted Tutorial: install Java on the IPhone by WithRat.

I found a program in the Package IPhone/Java ,and unpacked it,in the data.tar.gz file ,i found HelloJava.app,so i copied it to my iPod,and ran it .
It did run,but i couldn't see any windows on the screen. Using the ps command ,it was sure in the processes.
Does anybody know why?
Thanks
