jboss.org provides a home for the development of Java Enterprise Middleware in open source by an open community.

Open source means that the source code is freely available, distributable and modifiable by anyone who wishes to do so. This ensures that the software can evolve quickly and be reviewed at all times to maintain reliability, security and performance. The source code can also be very useful during development, allowing the exact operation of the software to be observed whilst it is running.

An open community means that anybody is free to contribute to a project and collaborate in the ongoing development. This allows the software to adapt quickly to users' needs and encourages innovation.

You are welcome to download and use any of the products (the binary releases) available on jboss.org, together with documentation, completely free of charge. Licensing terms can be found on the Projects page.

Help and support are also provided free of charge by the community: via the wiki, forums and mailing lists. Alternatively you can enquire about a commercial subscription from Red Hat.
