I have a similar question; we are using JBoss 3.2.7. We have our own shared JAR repository that we load by including the following in our server's jboss-service.xml file: I see all these classes listed in the LoaderRepository service. If I update one of the JARs, then via the jmx-console invoke the "flush" method of the LoaderRepository service, will it cause the loader to reload all the JARs, including the new one? If not, is there a mechanism to do this in a new JBoss version? Upgrading is an option for us. Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4040406#...
