"Replication not happening. Using wrong cache?"

Hi there,

apologies if this seems a noob question or has been answered a lot of times 
already but concise information is tough enough to come by.

we have a JBoss 3.2 cache set up on our cluster that contains 2 WebLogic 10.3 
managed servers with replication enabled and I've noticed that simple 
name/value pairs seem to be replicated in the cache just fine but TO objects, 
even ones with 5 or so String member variables are not.

The cache we're using is a plain TreeCache and I'm wondering if the TO objects 
aren't replicating because the TreeCache isn't designed to and I should be 
using PojoCache instead?

With that in mind, I'm looking at ways to speed up an application I have and 
want to use HashMaps to store database reference data (that doesn't change) to 
do the lookups in the Java code instead of firing more SQL off to the database 
servers.  I could use a singleton and HashMaps in the Java code but I'd like to 
move the lookup data into a cache outside of the app.  Would a PojoCache be the 
suitable cache type for a HashMap? Is the memory overhead too much overkill 
just to store some reference data?

Thanks in advance for any replies
