i want to remove the Dos window , while running the Java Application. i know it is possible by staring the aplication by javaw. but again this application could be started in a batch file only, as it has a lot of parameters. so if we use javaw in an batch file, the process starts without giving output in the dos window, but the dos window remains there because of the batch process started. i wanted to avoid this. i hope u folks understood what i mean. if not mail be back. a faster solution to this is appreciated.
