I have a JSP page that shows the web directory and some documents in it. The documents type include PDF, Word, and NRL file. When I click on PDF or word file, Windows Explorer knows to invoke Acrobat and MS Word. NRL is a iManage Document Management file which when I click opens up as txt in browser. What do I need to do in my JSP page to solve this problem so that when a user click on a NRL file, it will use NRL.EXE (This program comes with iManage) to open it.
