I have 8 jsp pages.Each of them has three columns:Left,Middle and Right.The left column consists of menu while the right column consists of News and Events. These two are same for every page.There's also an image of +,on clicking which a login form appears.
Only the middle column is different for each of the page.
How to write a code for login authentication so that it is valid for all the pages. Should I insert the loginform coding in each of the page.
Yes, you can use include file on every jsp page using
<%@ include file='login.jsp' %>
