[jira] Commented: (AMQ-1063) Journaled JDBC checkpoint fails with
java.io.IOException: Already started.
[ https://issues.apache.org/activemq/browse/AMQ-1063?page=comments#action_37496 ]
Ken Gallo commented on AMQ-1063:
--------------------------------
Do you have the mysql-connector-java.jar in the lib folder?
Do you have an activemq schema in your db?
It works in my Windows XP, Java 1.5.0_06, MySQL 5.0.24 environment.

> I am running trunk using JDBC against MySQL 5.0.27. I am seeing the above mentioned IOException. Do not have specific instructions on how to reproduce at the current time, but I was using durable subscriptions with the store durable cursor if that helps. (I'll post if I find out more information.)
