JBoss 4.0 troubles with H2.1.6 because of H2.1.5 jar

Hibernate version:2.1.6 ant later
JBoss version: 4.0.0

Be aware, JBoss 4.0.0 comes with Hibernate 2.1.5 in the distributive. The following configurations:
all, default, standard consist hibernate2.jar and cglib-full-2.0.1.jar from Hibernate 2.1.5.

Code:

INFO [net.sf.hibernate.cfg.Environment] Hibernate 2.1.5

I tried to put Hibernate 2.1.6 jars into my har, sar, ear but JBoss used classes from its <configuration>/lib directory and it were Hibernate 2.1.5. The possible solution that I found it is a replacement of jars in <configuration>/lib by new ones.

The question:
Does anybody know how to make JBoss 4.0.0 use Hibernate jars from har, sar, ear? In production deployment it would be easier to deploy only one application.ear that consists ejb.jar, hibernate.har, needed jars and etc.

That is currently not doable.

The effort needed to acheive that is way more than I have time for. Of course thats the beauty of open source; if you come up with the fix I'll consider it for commit.

It is believed that JBoss 5.x will include standard mechanisms to acheive this on behalf of services.

Why don't you just drop the Hibernate 2.1.6 jar into the JBoss lib directory (replacing the 2.1.5 jar)?

I think that the only caveat here would be if the implementation in 2.1.6 was incompatible with the JBoss/Hibernate HAR stuff.

Worth a try anyway...

Damien, I do it. But as I said, it makes production deployment a bit more complex. If you have 10 app servers you should copy it 10 times :) we have ant task for this, but our offshore customers .... :) (command lines, ant tasks and etc)

Steve, and what about updating hibernate jars in the jboss 4.0.0 distribution by new ones. Our customers (not only mine:) will download new jboss 4.0.1 distribution and will get all tings right. As I see hibernate team has working partnership with jboss group and with hibernate 2.1.6 jboss will get more better than with hibernate 2.1.5 ;)

2.1.6 is now the version included in jboss...

From what I understand, the Tomcat deployer in JBoss does something very similiar. Try taking a look at that code to see how it partitions the classloaders.
