Re: Request for help with new adapter/struts/hibernate

Thanks for the feedback. Logging issues in jira is pretty straightforward,
just create a user and use the 'create new issue' menu option. Our project
is called middlegen3 (should be chosen default if you access it through
the direct link to the project page -
http://jira.codehaus.org/secure/BrowseProject.jspa?id=10110).

So far I've only made minimal changes to the code originally contributed
by Dylan Etkin
(http://jira.codehaus.org/secure/ViewIssue.jspa?key=MIDDLEGEN-11).

I'm not quite familiar enough with Hibernate to know the best way to look
up the Factory. So far I've assumed it's deployed as an MBean available
with JNDI, which I have tested and found to work on JBoss (having deployed
Hibernate as a SAR file).

I guess the best way to solve this is to have different schemes to look up
the factory, we should probably generate some kind of lookup util that can
have a number of different implementations depending on the way hibernate
is to be deployed.
