Re: Vexing problem with Tomcat 5.0.28/Pointbase/JNDI/ConnectionPooling
This tells me a lot: Caused by: java.sql.SQLException: No suitable driver Make sure the driver .jar file is in common/lib and the driverClassName parameter of your ResourceParams element references the correct driver class (don't use a DataSource class here).

Re: Vexing problem with Tomcat 5.0.28/Pointbase/JNDI/ConnectionPooling
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!
