What about if you just have this jboss-classloading.xml in your deployment: | <classloading domain="some-name" xmlns="urn:jboss:classloading:1.0" name="some-name" | import-all="true" export-all="NON_EMPTY" version="0.0.0" | j2seClassLoadingCompliance="false" parentDomain="DefaultDomain" > and leave esb.deployer as it is. Or did you already try this? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4249443#...
