From my experience, this group is very lightly used and the chances of getting a reply to important questions are slim.
Are there any other JBoss forums that I could use? Of course, by my own argument, I'm unlikely to get an answer to that :)
Is there any strong reason at all to use case-preserving create-table DDL in the first place?
Have you tried including quotes into table-name in jbosscmp-jdbc.xml?
