Subject Re: Vexing problem with Tomcat 5.0.28/Pointbase/JNDI/ConnectionPooling
Date Mon, 13 Jun 2005 00:45:15 GMT
Hi David,

    Your suggestion solved the problem. I never realized that I had put in a 
wrong class for the driver. (I didn't have to do any of the other 
suggestions that you'd made in order to make it work). Thanks so much for 
spending your time on this and helping me out.

Thanks again!
