On Tuesday, we announced our New Development, Distribution, and Support Model for JBoss. As followup to that announcement, we have released the JBoss Enterprise Application Platform 4.2 Beta. Congratulations to the development team and community for helping us pull this Beta together!


You can access the Beta download from the JBoss Enterprise Middleware Downloads page.


JBoss Enterprise Application Platform integrates the following open source JBoss technologies for building, deploying and hosting enterprise Java applications and services:

  • JBoss Application Server 4.2
  • Apache Tomcat 6
  • JavaServer Faces 1.2
  • JBoss Clustering, Cache and Messaging
  • JBoss Transactions JTA
  • Hibernate
  • JBoss Seam


This Beta Release represents an opportunity to evaluate the JBoss Enterprise Application Platform before its widespread production release. It is intended as a technology preview in order to allow users to explore its capabilities and evaluate its suitability for their needs. Please deploy it in testing and evaluation environments only.


Your feedback on this technology preview is valuable to us, and is an integral part of making this the most stable Enterprise Application Platform possible. Please raise any concerns that you have or issues that you encounter by opening an issue in our JIRA Issue Tracking System at Please bear in mind that the JBoss Enterprise Application Platform Beta is a technology preview and will not have a support SLA until its final release.




JBoss' success has hinged on grassroots adoption by developers and users of our open source technologies. Thank you for your support over the years! With our relaunch of, we are hoping to fuel that innovative spirit further and keep our users informed and excited about our new technologies and directions.

There are many types of developers, of course. While many will download our open source components and tools and support themselves via our forums and wikis, many corporate developers just want a set of solid tools they can use and a well tested platform to develop and deploy on. While they may think innovation is cool...and will factor it into future applications...stability is what gets deployed today. They have a job to do and want vendors like Red Hat to make their lives simpler. Click here for more...
