As the error reads, you have to specify property order for org.jboss.aop.microcontainer.beans.metadata.AnnotationOverrideBeanMetaDataFactory. I don't know why XmlType specified on a super class is not visible. propOrder={} binds to model group all instead of sequence. Check out the javadoc for XmlType, it has an example and explanation. The last error says BeanMetaData is missing property order as well. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4229570#...
