Can I use TreeCacheAOP - thereby replicating only attributes that change, as opposed to replicating entire objects or sessions across servers - within JBOSS 3.2.6 with POJOs?
You can but it will take a lot of effort. As a matter of fact, I am implementing in jboss-head for the fine-grain http session replication down to the field level. So we will have granularity of SESSION, ATTRIBUTE, and FIELD.
I need couple weeks to test it out and then back port it back to 4.0.x release sometime.
