Debug level Hibernate log excerpt:

Hi - this is a newbie architectural question I hope someone has some input for... We have an environment with many web applications (using beehive pageflows/struts) running in Weblogic. They use a lot of reference data and I'd like to cache it in one place on the server rather than in many places for every application. I figure I need some sort of a central (yet local) data service layer, like local stateless session beans or something similar. However, I'm leary of introducing EJB's just for this. Is there another alternative?

I have briefly looked at the spring framework but it's not clear to me how to share the data among many apps on the same server.

Thanks in advance!

I've read about application level sessions that seem to be in the right direction. Is there such a thing as a "server level session"?

There is "such a thing" as the Hibernate second-level cache

Thanks for the reply Steve. 2nd level cache looks interesting. Would it be affected by the fact that each web application uses its own classloader even though they are running in the same jvm?
