JBoss® Enterprise Middleware from Red Hat takes the best projects and features from the JBoss Community, and other communities such as The Apache Software Foundation, and integrates them into a broad portfolio of stable, supported middleware product offerings that are maintainable over the long-term. JBoss Community projects can be downloaded by anyone at any stage of the software development process. These projects are used by developers to test and integrate middleware capabilities as a part of their application development efforts. However, due to their rapidly changing nature, lack of support, lack of integration, and the unavailability of certified binary patches/updates, open source community projects are best suited for proof-of-concept and development projects. This paper discusses the differences between JBoss Community projects and JBoss Enterprise Middleware products. It explains how JBoss Enterprise Middleware delivers the benefits of open source software, combined with the additional testing, certification, and maintenance releases necessary for reliable long-term enterprise production use.
