Global static variable. I just CANNOT get global for everything

Question

Hi,
I copied a connection pool example from oracle web site. It uses static variable. Its not a servlet, its a javabean. I can run a million times in one session and everything is great. If I open up another session, it creates another instance and creates more connections when it should be seeing the previous instance.
My question is how to make a static variable global to the entire application? Do i have to initialize it in the servlet container? All im doing is calling a JSP page which calls this bean. If instance is null, create 5 new connections. Well like i stated above, it works for a single session. It appears that each session gets its own instance. I have been working and debugging this for a long time and I just cannot come up with a solution...
Any ideas???
Thanks as always

Answer 1

Declar it as static within the servlet class.
public class MyServlet extends HttpServlet {
public static ConnectionPool pool;
Then you can access it from any JSP/Servlet using MyServlet.pool but you may have to import the class into the JSP/Servlet.
Be aware that there may be synchroniztion issues when you access this static object so you may want to synchronize access to the pool.
  synchronized (application) {
       if (MyServlet.pool == null) { //initialize pool code here }
