Your problem is that JBossXB knows how to resolve the schema and create the SchemaBinding. But the SchemaBinding has no object model bindings. JBossXB has scanned the schema for JAXB schema annotations and not found any and there is no initializer to populate the bindings either. It parsed the xml file but there were no callbacks registered to actually do anything. ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4110244#...
