Combine the path that JFileChooser undoubtedly returns with this: http://forums.sun.com/thread.jspa?threadID=760337

There might be more current solutions available, and in fact I wrote the exact program you're describing myself, but since my program is on my older machine... you're out of luck there.

Why on earth you want to use cmd.exe to open simple txt or doc files if you can use Apache POI?

actually i m just a beginner in Java and this code is one of the small part of my GUI that i m going to build....

any comments will be appreciated. thanks..

That piece of code will attempt to launch an application associated with the document formant under operating system with use of command line/prompt. In doing so you will move control from your java application to operating system. It is waste of time as this sort of things can be done through shell commands. If you wish to open/read/edit document through Java use an library like Apache POI or similar
