Subject: client program doesn't get exception for a http 500 staus response
From: ysliu...@gmail.com
To: java-user@axis.apache.org
I'm working with axis2 1.5.1, and try to use it as webservice client.when I try
to invoke a oneway webservice operation, I found if the server return http 500,
I didn't got any exception in client side.but for other status code, like, http
404, I can get an exception.I made some study on axis2 source code.and found
the logic in following method,
org.apache.axis2.transport.http.HTTPSender.handleResponse(MessageContext,
HttpMethodBase):
for HttpStatus.SC_INTERNAL_SERVER_ERROR || HttpStatus.SC_BAD_REQUEif the
operation is 2 way operation, set ProcessingFault to true for income
message.but for one way operation, there is no special action, except just try
to process the response.since 1 way operation doesn't expected a response soap
message, the response seems was discarded.I want to know is there any special
consideration for such behavior?should't a exception be thrown out when
response status code is 500 and operation is of one way?
MG>One way-operation in the west means as you soon as request arrives at
destination you never return
MG>Is One-way-operation classified differently in the East?
I inline the method I mentioned for convenient review.in addition, I checked
source of axis2 1.6, and found the behavior is as the same.

void handleResponse(MessageContext msgContext,
HttpMethodBase method) throws IOException { int statusCode =
method.getStatusCode(); log.trace("Handling response - " + statusCode);
if (statusCode == HttpStatus.SC_OK) { processResponse(method,
msgContext); } else if (statusCode == HttpStatus.SC_ACCEPTED) { }
else if (statusCode == HttpStatus.SC_INTERNAL_SERVER_ERROR ||
statusCode == HttpStatus.SC_BAD_REQUEST) { Header contenttypeHeader
=
method.getResponseHeader(HTTPConstants.HEADER_CONTENT_TYPE); String
value = null; if (contenttypeHeader != null) { value
= contenttypeHeader.getValue(); } OperationContext
opContext = msgContext.getOperationContext(); if(opContext!=null){
MessageContext inMessageContext =
opContext.getMessageContext(WSDLConstants.MESSAGE_LABEL_IN_VALUE);
if(inMessageContext!=null){
inMessageContext.setProcessingFault(true); } }
if (value != null) {
processResponse(method, msgContext); }
//should't a exception be thrown out here in a else branch like
//else{ // throw new
AxisFault(Messages.getMessage("transportError", String.valueOf(statusCode),
method.getStatusText())); //}
Object isTransportNonBlocking = msgContext.getProperty(
MessageContext.TRANSPORT_NON_BLOCKING); if
(isTransportNonBlocking != null && (Boolean)isTransportNonBlocking) {
throw new AxisFault(Messages.getMessage("transportError",
String.valueOf(statusCode),
method.getStatusText())); } } else { throw new
AxisFault(Messages.getMessage("transportError",
String.valueOf(statusCode),
method.getStatusText())); } }thanksysliu
