Re: Handling Database Connections

Hi James,

David's right; a singleton or a static class with a static initializer.

I would suggest some extra research to wrap the JTOpen classes so you
can use the code with any connection pool or datasource.

Last, knowing what you don't know is often more valuable.

David,
Thank you very much! I have heard of singleton classes, but I never really
read about them until today. This looks like it will work perfectly.

I've just been teaching myself Java and now I'm finally beginning to use
it
in production. I didn't realize how much I didn't know ;-)

Create a singleton class that creates the connection pool and then doles
out connections.
