Hi ,

I am implementing the functionality to count the no. of active users, which are currently loggedin to the system.
I am using HttpSessionListener interface to track the session count, bu the problem is that even if the user is just see the index page (welcome page)the session is created.
I want that, only if user will login then session will create. How can I do that?

connection.close() - it close the conection with the databse nad release all the resources.
con = null - the reference to connection object is deleted in that case if the connection are open then it still open i.e. resources are not free.

if (rs.next() == false) { } else { rs.previous(); }

rs.next() increase by 1 in if, if the record is their
then it wil execute the else block that time again decrese the count by 1 i.e. it again to its original position.

Hi Raghavan,

Could you please tell me how can I pass data from jsp to javascript using scriplet.

I have one question. In which scenario I use

RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(nextJSP); and
RequestDispatcher dispatcher = request.getRequestDispatcher(nextJSP);

I know their programming difference, but I am confuse with the question where and when and which method I will use.

Waiting for reply..

You can use singlton pattern also.
