Unfortunately I don't know how the issue can be fixed w/o doing that "complication" work. This is essential to work it out. This happens during marshalling, so I need - the XSD against which the object is marshalled; - the classes and initialization part of the object being marshalled. The hint to narrow it down is "Missing value for the required attribute strAttr of element {http://org.jboss.test.ws/jbws720/types}getProperty" View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4154171#...
