In going through the initial extraction of metadata out of jbossas, its seems that what needs to be done is: 1. The existing ObjectModelFactoryDeployer based deployers producing legacy metadata need to be converted to SchemaResolverDeployer type deployers that produce the new metadata, and then create the legacy wrapper using the new metadata as the delegate. The JBossXBBuilder would be used to create the SchemaBinding for the new metadata. One little issue here is that the SchemaResolverDeployer does not have a SchemaBindingResolver getResolver() method to allow subclasses to easily extend the default resolver. 2. Fix up misc uses of the legacy metadata. Missing methods, creation without the wrapper, etc. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4086639#...
