Not much point in storing a datasource as a session attribute (1 datasource per application user?). More appropriate
tomake it application-wide by putting a datasource in a servlet context or, as someone else suggested, a static
attribute/property/member/variable... request.getSession().getServletContext().setAttribute(...). JNDI is another
goodplace to put this sort of thing. An easy way to make sure your datasource is always available is to use a servlet
contextlistener to create it when the application is initialized. Google for servlet context lifecycle should tell you
howto do setup a listener.
Now, as for a null pointer on your connection object, maybe you have something misconfigured in your datasource.
Username,password, host, and driver class are usual suspects.

Not sure. You can post your code and maybe get some help. Wait, is this homework?
