As of today JBoss Messaging 1.2.0GA is integrated with JEMS Installer. So when user downloads JEMS Installer ( take the latest code from SVN https://svn.jboss.org/repos/installer/jems-installer/trunk/) and selects one of the profiles (eg all, default, ejb3, ejb3-clustered and jms ) from InstallationGroupPanel, on Packs panel there is option to either select JBoss MQ or use JBoss Messaging in mutually exclusive way. If user selects JBoss Messaging, installer gives an option to install either as standalone or clustered JBoss Messaging. This is good as it gives flexibility to user to install JBoss Messaging with EJB3/EJB3 Clustered. The only problem is that its not obvious that JEMS Installer is capable of installing JBoss Messaging and JBoss Messaging team needs to doccument this well.
