Question

jsp code to know which link is clicked in previous page, based on that to change the web page content of second page. Help me to write code for this.

Answer 1

Assuming you have one JSP for all links, do something like this:

main.jsp:

<ul>
  <li><a href="detail.jsp?link=page1">Page 1</a></li>
  <li><a href="detail.jsp?link=page2">Page 2</a></li>
</ul>

detail.jsp:

<h1>I am on Detail Page</h1>
<% String link = request.getParameter("link"); %>

Then use this variable as per your need.
