JBoss has released JBossCache version 1.2.4, 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.

JBoss Cache provides two caching APIs to suit your needs. The JBossCache API offers a traditional, tree-structured node-based cache and the JBossCacheAOP API, which builds on the JBossCache API, provides the ability to perform fine-grained replication of Java objects, resulting in maximum performance benefits.

JBoss Cache has a business friendly open source license that makes it free to download, use, embed, and distribute.

You can download it from http://sourceforge.net/project/showfiles.php?group_id=22866&package_id=102339&re
lease_id=365141 .
