(October 18, 2002) - The GemStone CMP Accelerator (from GemStone Systems, Inc), a shared transactional Java workspace that provides caching, clustering, and object persistence capabilities, now integrates with the JBoss Application Server, an open source, standards-compliant J2EE based application server implemented in 100% pure Java. The combined GemStone and JBoss technologies provide performance improvements for applications using Enterprise JavaBeans (EJB) with CMP 2.0.

The integrated technology offering from GemStone and JBoss was designed for applications using CMP at all stages-from the development of the application through to the deployment of production systems. The GemStone and JBoss solution can be deployed to revive existing applications with performance problems or issues. The product solution can also be established as a key piece of infrastructure prior to development to reduce hardware requirements and costs.

Features included with the GemStone CMP Accelerator on JBoss:

• Optimized Caching for CMP 2.0: GemStone CMP Accelerator on JBoss provides transparent caching mechanisms for EJB Entity Beans written to the Container Managed Persistence specification version 2.0. By maintaining object structures and direct object relationships, the cache keeps data in a state that is ready to be used by Java applications.
• High Availability: The GemStone fault tolerance technology continuously monitors and automatically restarts business processes. In case of total system failure, GemStone technology allows for easy fail-over to a backup system.
• XML deployment descriptor configuration: All information required to cache CMP 2.0 EntityBeans is maintained in an extended version of the JBoss Entity Deployment Descriptor. No code changes are required to the beans in order to take advantage of GemStone's caching features. The GemStone CMP Accelerator on JBoss technology can be used for an existing or new CMP 2.0 compliant application. The cache can be enabled and configured on a bean-by-bean basis, allowing for a fine-grained level of control.
