Ideally, you will package the necessary jar files with your application. The jars in the lib folder of JBoss are used by all the applications deployed on that server (including the ones which are shipped by default by JBoss). So replacing/adding jars in the lib folder of JBoss is always risky. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4175099#...
