retaining session variables

a servlet page is calling a a Jsp page, this jsp page contains a hyperlink. When i click on the hyperlink, i have to call a jsp page with some parameters. I want to know how to pass the parameters to the jsp page on click of the hyperlink.

Do we need to use the session if so how?

<a href="other.jsp?param1=a&param2=b">click</a>

will allow you to do:

    String a = request.getParameter( "param1" ) ;
    String b = request.getParameter( "param2" ) ;

in "other.jsp"

otherwise, yeah, you can store the values in the session...  but they will be in the session no matter if the user clicks the link or not (as the JSP session code will run before the user gets the html page)
