I have also seen this same error using a thin client. The first quesy throws a exception about closed connection then creates a new connection and carries on. I am using the same version of mysql but connector 3.1.6.. When i use the same client same queries against our hsqldb db we never get the problem. I have been working on the hsqldb side for a while and assumed it was an error in my code which i would fix later. i have a newer version of mysql 4.1.12 which is our new base line so i will try it out on this database and let you know.. But it sounds like a bug in the driver?

Database version: mysql-connector-java-3.0.16-ga-bin.jar mysql-4.1.9 To reproduce I open the website on the index page and then close the browser, the next day I open the browser again and I get the error. The error comes from the connection pool, I find this in my Catalina.out log: DEBUG [http-80-Processor25] - Returned connection 12839271 to pool. (This was the day before) DEBUG [http-80-Processor24] - Checked out connection 12839271 from pool. (The connection for the paginated list on my index.shtml page) DEBUG [http-80-Processor24] - {conn-100045} Connection DEBUG [http-80-Processor24] - A bad connection (12839271) attempted to return to the pool, discarding connection. The query fails and the index page comes up and prints the exception trace. Pressing F5 reloads the page and fetches a new connection that succeeds. The connection is used for: setEmployeeList(dailyBulletinService.getOutStaff()); Is this enough info?

Meindert, Please provide more information. I can't really tell what is happening in your situation. If you Servlet Session is timing out it should have not affect on the database connection. My notion is that it is something else. Please provide the database and driver with versions that you are using and a more specific description of what the application is doing when you experience this error.
