Session in the servlet

Hi!

A Netbeans web application use some servlets, not jsp, and tomcat, and postgre sql.

The big problem is executing some querry after the jdbc connection was closed, or can't open a new jdbc connection because too many are open, for example. And the session in some situations lost who is the logined user :) This was the application probem. If you have any idea to solve tham please anounce me.

My problem is I don't know how to check if the session is valid or not in the folowing function:

protected void processRequest(HttpServletRequest request, HttpServletResponse response){

request.getSession();

// how to check that session?

}
