Your find might have been a bit too specific, since you mustn't have any jars for any version of Hibernate or MySQL in your webapp's classloader branch, other than in WEB-INF/lib. > There is a link to the mysql driver jar in hibernate-3.0's > own lib directory. What do you mean by "hibernate-3.0's own lib directory"? Is this a link somehow inside the Hibernate jar? Are the Hibernate classes somewhere else besides the jar in WEB-INF/lib? > When I re-run the application, I am right back where I was. I > get "java.lang.ClassNotFoundException: com.mysql.jdbc.Driver". What's in the <Context> element for your webapp? Since you're using C3P0 pooling, you should not have a <Resource> element inside the <Context>, otherwise Tomcat will also attempt to do pooling for the driver. > My webapp cannot see the mysql driver jar, although it clearly > sees the hibernate jar. Post the complete stack trace for the CNFE. Still sounds like you've got another copy or version of the MySQL jar around, causing classloader conflicts. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
