Hi, Has anybody managed to successfully configure classloading isolation in JBOSS 4.2.2 GA? I tried http://www.jboss.org/community/wiki/classloadingconfiguration without any success. Also tried hints from several other sites. http://www.mastertheboss.com/en/jboss-application-server/141-jboss-classl... I am confused about the statement that in 4.2.1 they changed something, what about 4.2.2? Will it work or not? I find the description contradictorily: once it is written to use ":archive" and next line I read ":loader" . What should I use? How is the correct syntax? The com.example:archive=unique-archive-name strings are JMX ObjectName .... For example, for a petstore.ear file, use: com.example:loader=petstore.ear as the repository name. What about :loader option in loader-repository? How does it fit together with :archive? Can they be used together or they are mutually exclusive? additional question: what influence does it have to set Java2ClassLoadingCompliance in jetty or tomcat configuration. Will this conflict with the isolation settings for a war? Or with the settings in deploy/ear-deployer.xml ? I would be glad if someone pointed me to the right direction and helped me out of my classloader hell.
