JBoss.org Community Documentation
Pojo Cache is an extension of the core JBoss Cache API. Pojo Cache offers additional functionality such as:
maintaining object references even after replication or persistence.
fine grained replication, where only modified object fields are replicated.
"API-less" clustering model where pojos are simply annotated as being clustered.
Pojo Cache has a complete and separate set of documentation, including a user guide, FAQ and tutorial and as such, Pojo Cache is not discussed further in this book.
Pojo Cache deployment in the JBoss AS5 is discussed more in Section 8.5, “Pojo Cache Deployment Options”
