We are using Oracle815 with Thin Drivers(classes12.zip) in our
JRUN is that 815 does not support conn.pooling

Answer 1

Are you using a Singleton pattern? Maybe you are inadvertantly creating many pool instances instead of using the same pool all the time?
I finally see what you are trying to do in your free method, and I would still suggest rethinking this. Usually you close the statement and result sets where you have used them in your code ...possibly in a dafai block ...er, sorry ...a finally block.
Maybe your problem stems from your altered free method, or maybe you are accidentally creating more than just one single instance of the pool. What is your max and initial connections set to? Do they exceeed the limitations of your database configuration for concurrent connections?
Since this is a version of the original Marty Hall pool, would you like to try a link to his pool ver batim? You could replace your pool with one we know works?
