Consider a servlet which accepts 2 parameters.
You need to invoke this servlet when the user clicks the hyperlinke "CallServlet".
Now on clicking this "CallServlet" hyperlink that CallServlet.java should be invoked. This "CallServlet" takes 2 input parameters. To pass those 2 input parameters you can use url re-writing.
For ex
res.sendRedirect("CallServlet?param1=value1¶m2=value");

So here CallServlet url is appended with param1=value1¶m2=value2.
