That would be clear to me. | That, and JBoss AS ships with configurations for JBoss Cache that is tuned and configured. "eric.hubert" wrote : | I already use this configuration inside JBoss. The problem is that I don't know which places I have to adjust to make it working in Glassfish. Could you please assist! | TBH, I've never used this in Glassfish so anything I say is purely theoretical. :-) In fact, we have wiki pages on running JBC on WebLogic and on WebSphere. I'm sure a lot of people would appreciate your contributing your findings, tips and tricks for Glassfish as well. The TreeCacheProvider hook looks up the JBoss Cache instance in JMX, bound under a specific name. You may want to write your own hook - this is a pretty simple class, have a look a Hibernate docs - which will look up a JBC instance in JMX (or JNDI) and if it doesn't exist, create it from a cache cfg file (and probably bind to JMX/JNDI again).
