The problem you are dealing with involving JMS errors in the log files is how you have the server setup. Did you select the default settings for JBoss when it cam to your data source? If not, the installation went out to the database and created several tables used for JMS. The next time you start your server, you will see the same processs over and over--JBoss trying to create tables, but they're already there.... You will find having log4j.jar file in your projects.....causing you many hours of troubleshooting errors. Many error reportings are cause by the duplicate log4j.jar issue. You will be filling up those log files quickly! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4012265#...
