i tried the include tag of JSP tag library. but its still static.i want a dynamic thing. like only after clicking the link it should show Hello in the Same index.jsp.
To understand the following suggestion or enhance it even you will need some knowledge of HTML forms. So here we go:-
In your index.jsp create an HTML form with an input field (it could be hiddent or a text field) named "hello" and another "Submit" button for that form. Also set the "action" field of that form to the same index.jsp.
Alternatively you could also simulate a HTTP GET request by using the anchor element (<a> tag). for example "http://...../sample.jsp?user=cdf" is equivalent to a form with an input element "user" being posted to file "sample.jsp"using the "HTTP GET" method.
Next in your JSP section check for the occurrence of the parameter named "hello", using request.getParameter("hello"); .
If you get any value for this other than a "null", that would mean you have been directed to this page, after you clicked the submit button on your form.
So in case you do not get the "null" just print "Hello" or any other text you wish using a normal "if" check.
