Java EE (Java Enterprise Edition) General Discussion

Hi,

I have a problem with my deployed web application. At first, I thought Glassfish was messing up on me, and after checking the log I could see plenty of null pointer exceptions being thrown at lines in my code where I generate prepared statements from my connection object. I have been initialising my connection in the Init() method of all my classes, and equally, I've been closing it in Destroy(). I can only imagine that destroy() isn't being called - since the log clearly shows "connection success" messages but not "connection closed" messages. I am connecting to the servlets via a J2ME app on my mobile phone. Does connecting in this way somehow not invoke the destroy method when the servlets work is complete? Am I going to need to move all my connection initilisation and closing into the necessary doGet/doPost methods of each of my servlets?
