Overriding  portal JSP

Implementing Hook is an easy way to modify existing portal source, here we can see how to modify a jsp. if we want to  do some changes or modification in any of the existing or Out-Of-The-Box portlet, we can go for jspHook.

  

For example:

          In  ‘Document_Library’, if we want to do some modification or some changes or if you want  to   give any information in that portlet we can go for view.jsp or some other relevant jsp (it is in   webapps/root/html/portlet/document_library/view.jsp)
