If you only have a few servlets and the traffic is not that heavy you can open/close connection in your servlet. However you should open connection in init method and close it in destroy method so that they are done only once in the life time of the servlet. Make sure the method signatures are right so that they really override the ones in super class.

If you have many servlets and have heavy traffic it is a good idea to setup a connection pool.

I'm trying to figure out if I should be creating and closing my connections to the JDBC each time a servlet is called or should I just open it once and leave it open? ie: public void performTask(HttpServletRequest req, HttpServletResponse resp) {
                sess = req.getSession(true);
                customer = (Customer) sess.getAttribute("customer");
                createAuditTrail = false;
                try {
                        //!---New code put in Jun 2, 2005
                        if (ds == null)
                                getDS();
                        conn = ds.getConnection();
                        dmd = conn.getMetaData();

code here.....


                conn.close();

is this efficient or am I wasting valuable resources?  Thanks,
