Hi,

I have Jbpm 3.2.6 running on a Windows 2008 server, with Tomcat 5.0.28 and MySQL 5.0.27 as the DB running on local windows machine. It works perfectly.

As soon as I use MySQL 5.0.67 on a separate linux server (SLES11), and use that as my db/datasource with the exact same data/permissions, I get exception saying that tables cannot be found. Basically, it says no tables exist, even when I can see that they do. Tomcat shows me the following exception: 
WARN JbpmJobExecutor at 10.11.5.61:1 org.hibernate.util.JDBCExceptionReporter - SQL Error: 1146, SQLState: 42S02

And it's not just 'jbpm3.JBPM_JOB' that apparently doesn't exist, it happens everywhere jbpm tries to access the db.

Does anyone know why JBPM 3.2.6 is not working on MySQL 5.0.67 when its running on a linux operating system?
