Hi,
I need to use renaming/copying commands, coz my source filename and target
file name are same ! So im using the usual technique, writing to a new file
and renaming it as old file.
afa spawning a process, i found a Runtime.exec() method, but my goal is to
run the javac compiler to compile a java file, from the application itself.
i tried it a couple of times and both the times my ide crashed. is it
possible ? any ideas. im also working at it and wll let know. meanwhile, if
anybody had done similar things successfully pls share.

Thanks
