JBoss AS 4.2.3.GA Release Notes

This is the 3rd bug fixing release of the JBoss Application Server v4.2 series. The aim of this release is to provide fixes for bugs reported by the community against previous JBossAS v4.2.x releases. There were some backwards compatible component upgrades so switching to AS 4.2.3.GA from a previous 4.2.0/4.2.1/4.2.2 release should not present any problems. Please check out the Detailed Release Notes section for the full details.

A secondary target for this release was to improve support for Java 6. JBossAS 4.2.3.GA can be build with both JDK5 and JDK6. The JDK5 compiled binaries have undergone more rigorous testing, they constitute our certified version and can run under both Java 5 & 6 VMs (with a few configuration changes for JDK6, see the configuration section below). The JDK6 compiled binaries include support for the JDBC 4 APIs, but this should be considered experimental at this point.

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 AS 4.2 is also used as the basis for the JBoss Enterprise Application Platform. The Application Platform bundles JBoss AS and JBoss Seam  in a software package 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.
