start is a command of cmd. So run it instead:
Process p = Runtime.getRuntime().exec("cmd /c start cppexe.bat");

How to create lnk files, a close friend asked me today.

My thoughts:
Sample VB code is in http://wss.hypermart.net/vb/shortcut.html
Another simpler option may be to just create a batch file (.bat) file which the users and double-click to run the application (same as a lnk file).
Creating it is much simpler. Create a file with .bat extension and write the same command as you would while running it from comand line.
