[Building Sakai] Hibernate DocType DTD files and slow Sakai startups

[Noah Botimer]

Rob,

In general, JBoss is unsupported territory. It might work, but I'm unaware of any production institutions with commitments to community maintenance (in fact, I can't name anyone running JBoss in production).

I understand that there are various institutional preferences, but encourage you to take a look at Tomcat to see if there are specific barriers. If there are, maybe the community can help you address them so that you can be on a common platform.

I can't say whether this particular case is affected by using JBoss or not, but there is no QA done outside of Tomcat. It's hard to say whether there will be other quirks that come up with little container differences.

Thanks,
-Noah
