Sorry, its on top of MySQL
As usual on these forums, I end up answering my own questions.
If anyone is following this, debugs are turned on in the log4j properties file. A move toward consistency I suppose.
The JDBC logs appear valid, yet still nothing in the database and no errors in the log. In the absence of real help I will keep digging.
Just inspected the MySQL logs. Looks like a rollback occurs on every insert.
For the sanity of anyone following my thread in the future: The build I have always does a rollback. There is no commit. Everything worked fine when I placed my own commit in there, but of course that was just a check. Also, no problems with the "mm" Mysql JDBC driver (version 11).
