I think there is a big difference between default and recommended. HSql is
good for getting started quickly - but it has limits that need to be
understood and accepted if it is to be used. These are dependant on its use
- not on jboss - so use it - but at your own risk and investigate the hsql
site for its limits.

There is a client that comes with hsql - have you tried that - see hsql site
for more details.

Have you got the jaws.xml flag set such that tables are dropped when the
application finishes - if this is set, it should mean that the tables are
re-created upon startup - curing your problem.
You will see messages in the jboss log indicating it is creating (or failing
to) your tables.
The default setting is to create the tables on startup, but to NOT drop them
on close.
HTH,
Chris
