Just to follow up on this, the settings below work - but HSQLDB
doesn't seem to support nested transactions.
<<< beginning the transaction >>>
DBTest >> javax.transaction.NotSupportedException: Nested transactions not suppo

The DBTest class is from the JOTM + Tomcat example at
http://jotm.objectweb.org/current/jotm/doc/howto-tomcat-jotm.html.
Changing to use MySQL solves the problem and everything works great.
Also, it looks like JOTM (or maybe Carol) has issues with JDK 5. I
googled for the following error and it appears to be known about on
the ObjectWeb mailing lists - but there doesn't seem to be a
documented solution.
java.lang.NoSuchMethodError:
