From the 5.0.0.Beta3 release notes:
JBoss Messaging is a high performance JMS provider in the JBoss Enterprise Middleware Stack (JEMS), included with JBoss 5 as the default messaging provider. It is also the backbone of the JBoss ESB infrastructure. JBoss Messaging is a complete rewrite of JBossMQ, which is the default JMS provider for the JBoss AS 4.x series.
Some examples queues can be found in ./deploy/messaging/destinations-service.xml
From the 4.2.1.GA release notes:
JBoss Web v2.x is the web container in JBossAS 4.2, an implementation based on Apache Tomcat that includes the Apache Portable Runtime (APR) and Tomcat native technologies to achieve scalability and performance characteristics that match and exceed the Apache Http server. In the absence of the native libraries, JBoss Web falls back to the standard non-native connector mode. The native libraries need to be downloaded and installed separately in JBOSS_HOME/bin/native.
Tomcat 6 is now bundled as part of JBoss Web. deploy/jbossweb-tomcat55.sar has been replaced by deploy/jboss-web.deployer.
