Hi all, I got a problem when use JBoss Cache 1.4.0 within JBoss AS 4.0.2.
I have two application servers. when they start up, the caches can find each other, and fetch the in-memory status successfully. But when I put an object into cache A, it does not replicate the object to cache B; however, when I remove this object from A, it's also removed from B....

Yes, the insert is not replicated while the removing is replicated successfully.

what's wrong with my configuration? Please help me.
