The same thing happens with jboss 4.0.5.GA (installed using JEMS installer - thus including jbossws-1.0.3.SP1 (date=200609291417) when defining WebServices using JSR 181 annotations applied to EJB3 Stateless Session Beans. Seems like any parameter of a type defined within an inheritence tree where some of the levels do not add additional getter/setter properties (bug e.g. virtual methods) will lead to a duplication of getter/setter properties in the derived levels. Currently I am using a boolean dummy field (called jbossNoPropertyInClassBug) to avoid external client stub generators to fail on generatin valid stubs with the jboss generated wsdl.
