cache frequently accessed Java objects

 JBoss Cache is a product designed to cache frequently accessed Java
 objects in order to dramatically improve the performance of e-business
 applications. By eliminating unnecessary database access, JBoss Cache
 decreases network traffic and increases the scalability of
 applications.
 .
 But JBoss Cache is much more than a simple cache. JBoss Cache provides
 fully transactional features as well as a highly configurable set of
 options to deal with concurrent data access in the most efficient
 manner possible for your application. In addition, it is a clustered
 cache that replicates contents to other cache instances running on
 separate JVMs, servers or even entire networks, making JBoss Cache a
 highly efficient library used by application server developers to
 implement clustering features.
 .
 JBoss Cache provides two caching APIs to suit your needs. The JBoss
 Cache API offers a traditional, tree-structured, node-based cache and
 the Pojo Cache API, which builds on the JBoss Cache API, provides the
 ability to perform object-based, fine-grained replication of Java
 objects, resulting in maximum performance benefits.
