Its hard to say something concrete on your issue, you need to do some research first and provide more information.
after deploying par files in nwds 7.3 some of the jsp pages are getting jspparse exceptions.
providing that is by far not enough: did you tried to reduce the jsp source to find out what exactly is the problem? Where is the source of the jsp that brings you into trouble? What are "par files" and why you trying to deploy par on 7.3 at all? What is your environment?
