   public interface OnewayListener {  // Public Instance Methods  public abstract void onMessage(javax.xml.soap.SOAPMessage message); }   The  OnewayListener  interface is implemented by a  JAXMServlet  subclass that receives a SOAP message but does not wish to return an immediate response. The  onMessage( )  method is called whenever a message is received and is provided with a  SOAPMessage  object created from that message as its only argument. The implementation may handle the message immediately or defer its processing to a more convenient time. 
  A JAXM client that implements this interface and wishes to return a reply message must create the message using the  MessageFactory  of the JAXM profile that it is using, set the destination address using a profile-specific method, and then call the  ProviderConnection   send( )  method. See the description of the  JAXMServlet  for information on obtaining an appropriate  MessageFactory  .
