I've created a new Appfuse project using appfuse-basic-struts archetype and version 2.0-m4-SNAPSHOT.
During running the "mvn integration-test" I got the following Exception:

There is a problem with the mysql-connector-java driver version 5.0.4. Please see:
http://forums.mysql.com/read.php?39,139534,139889#msg-139889

After downgrading to 5.0.3 like in Milestone3 every thing went fine.
Afterwords I tried to upgrade it do the version 5.0.5. I got an exception because the version 5.0.5 is not yet available in the maven remote repository. So installed it to my local maven repository. Now every thing runs fine.

Pls decide weather to update or to downgrade. Pls find attached the to patches.

Best Regards
