Mike,
If you look closer at the examples, you will see that the DataSource is kept for
the life of the bean, but the connection is only kept for the life of each
method's use of if. I would try moving the opening and closing of the connection
into the method that needs it. You appear to be opening and closing the
connection in several places.
Hope that helps some.
