So for a ESB 4.x scoped deployment users will be required to create a META-INF/jboss-classloading.xml: <classloading xmlns="urn:jboss:classloading:1.0" domain="simple-scoped" parent-first="false" /> | which will "replace" the 'loader-repository' element in META-INF/deployment.xml: <jbossesb-deployment> | <loader-repository> | org.jboss.soa.esb:loader=simple-scoped | <loader-repository-config> | java2ParentDelegaton=false | </loader-repository-config> | </loader-repository> | </jbossesb-deployment> The 'loader-repository' element can be left but will be ignored by the AS 5 esb deployers. /Daniel View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4227683#...
