warning on startup with messaging

[mwaschkowski]

Hi,

With the messaging deployment I get the following warning on the console, how can I fix this? I don't get this with any other deployments...

Thanks,

Mark

This is because you are (probably) using HSQL.

HSQL does not support transaction isolation, so we give you a warning.

For any production system you must use a more production grade database, e.g. mysql, oracle, postgres, db2, sybase etc.

See http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfigJBossMQDB for more info.

Also see http://hsqldb.org/web/hsqlFAQ.html#FAQ

Tim, I think we should have our own explanation page for this on our user wiki http://www.jboss.com/wiki/Wiki.jsp?page=JBossMessaging, since I expect this will be a question that will be asked a lot. Do you want to start it?

OK, sound good, thanks.

I was worried that this might be something that was related to the other problem that I am having (another post with some details shortly).
