Okay this is a ridiculous question, but I'm still puzzled of what's going on. I'm creating a small ConnectionPool which just does the standard thing of holding a pool of connections to the db, and the class implements the Runnable interface. What I'm trying to do, is to dynamically create an array of these ConnectionPool objects, so that I can create seperate pools for each of our databases. Sounds simple, but everytime I try to initialize each ConnectionPool, I get a NullPointerException. If I create the ConnectionPool by itself (ie. without putting it into an array), it works just fine. Can anyone point me in the right direction? What's going on? thanks in advance..    More>>
