Bare is an implementation detail from the Java domain. Neither in the abstract contract (i.e. 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;
			
			...
}
