Regarding http://jira.jboss.com/jira/browse/JBAS-3047, I did some adjustments on top of Scott's changes, that I want them to be reviewed. They way I understand it is: a) To use the jboss web loader, either it has to be configured as the default setting for tomcat, OR a <loader-repository> entry in jboss-web.xml will activate it. In this case the parent/child first classloading behaviour is controlled by loader-repository java2ParentDelegation, and the java2ClassLoadingCompliance flag is ignored, e.g: | <class-loading java2ClassLoadingCompliance='false'> | <loader-repository>dot.com:loader=unique-archive-name | <loader-repository-config>java2ParentDelegaton=true | </loader-repository-config> | </loader-repository> | </class-loading> | b) if the web loader is used, then jboss-web.xml can override the tomcat configured default java2ClassLoadingCompliance setting, e.g: | <class-loading java2ClassLoadingCompliance='true'> | Is this correct?
