10.4. Document/Literal (Bare)

Bare is an implementation detail from the Java domain. Neither in the abstract contract (for instance, wsdl+schema) nor at the SOAP message level is a bare endpoint recognizable. A bare endpoint or client uses a Java bean that represents the entire document payload.
@WebService
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
public class DocBareServiceImpl
{
   @WebMethod
   public SubmitBareResponse submitPO(SubmitBareRequest poRequest)
   {
      ...
   }
}
The trick is that the Java beans representing the payload contain JAXB annotations that define how the payload is represented on the wire.
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "SubmitBareRequest", namespace="http://soapbinding.samples.jaxws.ws.test.jboss.org/", propOrder = { "product" })
@XmlRootElement(namespace="http://soapbinding.samples.jaxws.ws.test.jboss.org/", name = "SubmitPO")
public class SubmitBareRequest
{
   @XmlElement(namespace="http://soapbinding.samples.jaxws.ws.test.jboss.org/",  required = true)
   private String product;

   ...
}
