There are several ClassLoadingMetaData types. The org.jboss.metadata.web.jboss.ClassLoadingMetaData would only be set for a war with a jboss-web.xml that includes a scoped class loader metadata element. There is code in the AbstractWarDeployer to always set this if it was not obtained from the parsing layer, but this is now obsolete information. There is a DeploymentUnit org.jboss.deployers.structure.spi.classloading.ClassLoaderMetaData attachment that drives the new class loaders. Is that what your looking for? What do you need from ClassLoadingMetaData? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4126298#...
