Hello John, Well, I have been using the classes12.jar in TOMCAT_HOME/common/lib. I've used it with both the JNDI javax.sql.DataSource deal provided by the Jakarta-Commons project and another connection pooler. I've never had a single problem. I've used JDK-1.3.x and JDK-1.4 and haven't had to remove any classes from anywhere. If you are having to do this with Tomcat-4.0.3, I suggest an upgrade to the latest 4.0.4 or 4.1.x betas. They are plenty stable and fix some classloading issues. I pretty much skipped from Tomcat-4.0.2-b2 to nightly builds of 4.1 because of so many classloading issues with the final release of 4.0.2 (and 4.0.3 is just 4.0.2 + a security fix).
