JBoss AS 4.2.0.GA Release Notes

This is the final release of JBoss Application Server v4.2.0. JBoss AS 4.2 is a stepping stone from JBoss 4.0 to JBoss 5.0. It combines a lot (but not all) of the exciting new features of JBoss 5, but based on the stable 4.x MicroKernel architecture.

JBoss 4.2 is also used as the basis for the JBoss Enterprise Application Platform. The platform bundles JBoss AS 4.2 and JBoss Seam and it constitutes the software for which commercial support is offered by JBoss/Red Hat. Please read Sacha's blog if you are interested to learn more about the new development, distribution and support model for JBoss.

For information on the APIs that make up Java EE 1.4, see Java EE v1.4 Documentation. For a comprehensive tutorial on Java EE 1.4, see The Java EE™ 1.4 Tutorial. A jboss-4.2.x getting started guide that is based on contents from the tutorial can be found in JBoss Application Server Documentation Library

Note: The 4.2.x release of the JBoss Application Server provides support for certain JavaEE5 features, such as EJB3, but it is not Java EE5 certified.
