Hibernate connections to MySQL my db are not closing. After clicking 10 times in like 10 second, I get this connection statistics from MySQL Workbench (in my development machine. I'm the only user).MySQL Workbench Server Status
I have those in place

The code-block I call in everytime where I want to close the session.
if (session == null)
return;
if (session.isOpen()) {
if (session.isDirty())
session.flush();
session.close();
System.out.println("Session closed");
}
Do I miss something?
Well it seems I was creating SessionFactory everytime. There's a nice class here at the link, making SessionFactory static solved the problem. http://docs.jboss.org/hibernate/core/3.3/reference/en/html/tutorial.html#tutorial-firstapp-helpers
