Subject one-way notification in Axis?
Date Mon, 03 Jun 2002 08:25:56 GMT
I tried to use invokeOneWay to send a callback notification to a client without expecting any
reply but Axis replies with: "SaxException: The document's root element could not be found"
.
 
This comes from the HTTP-reply message doesn't contain any message at all since it's a pure
"notification" and not a "SolicitResponse" style of interaction. I guess that axis is looking
for a SOAP-envelop. Is there a way around this limitation and make it a "pure" notification.
 
The code I'm using to invoke the callback notification looks like this:
 
        Service  service = new Service();
        Call     call    = (Call) service.createCall();
 
        call.setTargetEndpointAddress( myCallback.getUrl() );
        call.setOperationName( new QName("testnamespace", "Notification") );
        call.addParameter( "result", XMLType.XSD_STRING, ParameterMode.IN);
        call.addParameter("transactionId", XMLType.XSD_STRING, ParameterMode.IN);
        call.setReturnType( XMLType.AXIS_VOID );
 
        call.invokeOneWay(new Object[] { "success", myCallback.getTransactionId()} );
 
The "log" from tcpmon looks like the following:

Response:
HTTP/1.1 200 OK
Content-Length: 0

Server: Apache Tomcat/4.0.2 (HTTP/1.1 Connector)
 
(invoking the service with "invoke(new Object[] {"astring", "2destring"} );" got rid of the
object references, so that also seems to be a "bug" in invokeOneWay, otherwise the same problems.
 
It would be great if someone had any insight into this.
