[hibernate-dev] Hibernate 3.4 + JBoss Cache 2.5 question on stackoverflow

It's semi-maintained, but TBH it seems rather convoluted and thus  

I've opened https://jira.jboss.org/jira/browse/JBAS-7411 for this and  
will post a link to that on the stackoverflow thread.

There's a deployer that parses a hibernate.cfg.xml into a metadata  
object, which includes the set of configuration properties stored as a  
key/value pairs. But the property names you use have to map to  
properties on the org.jboss.hibernate.jmx.Hibernate class, because the  
deployer uses JBoss MC property injection to populate the  
o.j.h.jmx.Hibernate object. So you can't use the regular Hibernate  
property names, which include '.' and such.  Plus it breaks when  
Hibernate adds a new property, a la what this user is seeing.

In its start() method the org.jboss.hibernate.jmx.Hibernate class then  
builds a Hibernate Configuration object, by mapping it's property  
values back to the standard Hibernate configuration property names.

More sensible IMHO is to inject into the o.j.h.jmx.Hibernate object  
the original set of parsed key/value pairs via a new setProperties 
(Set<BaseNamedElement>) method. The start() method would then build  
the Configuration from that set of properties. This would allow any  
valid Hibernate property to be used and would remove the need to use  
AS-specific property names. The Hibernate MBean interface would then  
just expose whatever properties we've chosen to map.

We should of course also support the legacy AS-specific property names.
