1: java event
2:java event calls a php function to apache.
3: which calls a window.bat
4: calls a php command line
5. calls a php daemon, which is a 'waiting server process', listening
on on a port.
6. you execute a command line statement
7. and it's for a php script to return something

What do you have at the beginning, and what do you want at the end of
this process. Break it down into simple steps. And then not only can
any php programmer help you, but any computer scientist can help you
utilize the control flow logic.
