I looked at source code generated by WSImport and there is something weird that doesn't compile: @XmlRootElement(...) | @XmlType(...) | @XmlAccessorType(XmlAccessType.FIELD) | public class MyOperationResponse { | @XmlElement(namespace = "", name = "return") | private MyValueObject return; | public MyValueObject getReturn() { | return this.return; | } | public void setReturn(MyValueObject return) { | this.return = return; | } | } The "return" keyword is reserved and can not be used as attribute, argument... The input interface was pretty simple: @WebService(...) | public interface MyWebService { | @WebMethod | MyValueObject myOperation(String myArgument) throws MyException; | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4107198#...
