Have the servlet take the current time in the begining, add it to the session and have the JSP take it again at the end of its code. Calculate the difference and print it.

Or do it by Javascript: on submission, add a timestamp argument, and parse and display it onLoad, using the client time both times. Much more acurate.

my JSP is already sending a timestamp value to stop server cache.

like when i submit my JSP, the url becomes

http://machine:8080/myjsp?timestamp=12345678&some_more_params...

>Or do it by Javascript: on submission, add a timestamp argument, and >parse and display it onLoad, using the client time both times. Much more >acurate

please provide a sample code architecture. not getting your idea.

In case you didn't know, a JSP is a servlet - the JSP container converts your JSP page to a servlet. Just add some Java code to your JSP:

<%-- at the top of the page --%>

<% long startTime = System.currentTimeMillis(); %>

<%-- at the bottom of the page --%>

<% long totalTime = System.currentTimeMillis() - startTime; %>

render time: <%= totalTime %>
