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.
