-----------------------------------
Assignee: Willem Jiang
> CxfClientCallback should not populate camel exchange OUT message if no
> response comes back to cxf producer and camel exchange pattern is InOnly
> -----------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: CAMEL-7338
> URL: https://issues.apache.org/jira/browse/CAMEL-7338
> Project: Camel
> Issue Type: Bug
> Components: camel-cxf
> Affects Versions: 2.10.4
> Reporter: Joe Luo
> Assignee: Willem Jiang
> Attachments: patch.txt

>
> I have a following camel route:
> {code}
> String destination = "cxf:http://localhost:9090/test?dataFormat=MESSAGE";;
> from("jms:queue:dslSource")
> .onException(java.net.ConnectException.class, Exception.class)
> .maximumRedeliveries(3)
> .maximumRedeliveryDelay(3000)
> .retryAttemptedLogLevel(LoggingLevel.INFO)
> .log(LoggingLevel.WARN, "Failed to send message ${body}")
> .log(LoggingLevel.WARN, "Sending message to the error queue:
> ${body}") // body is null here
> .to("jms:queue:dslError")
> .end()
> .log(LoggingLevel.INFO, "Sending message ...")
> .setHeader("bridgeDestination", constant(destination))
> .to(destination)
> .log(LoggingLevel.INFO, "received back: ${body}")
> .routeId("example-dsl");
> {code}
> If an exception is thrown, for instance, a ConnectionException due to
> unavailability of the backend web service, the onException() route will be
> executed. The first log endpoint:
> {code}
> .log(LoggingLevel.WARN, "Failed to send message ${body}")
> {code}
> prints out camel exchange IN message body without any problem. However, the
> second log endpoint:
> {code}
> .log(LoggingLevel.WARN, "Sending message to the error queue: ${body}")
> {code}
> only prints out a "null".
> The reason is that when an exception is thrown, the
> CxfClientCallback.handleException() is called:
> {code}
> public void handleException(Map<String, Object> ctx, Throwable ex) {
> ....
> if (!boi.getOperationInfo().isOneWay()) {
> // copy the InMessage header to OutMessage header
>
> camelExchange.getOut().getHeaders().putAll(camelExchange.getIn().getHeaders());
> binding.populateExchangeFromCxfResponse(camelExchange,
> cxfExchange, ctx);
> camelAsyncCallback.done(false);
> }
> ...
> {code}
> and this line always populates camel exchange OUT message regardless whether
> there is a CXF response back or not:
> {code}
> camelExchange.getOut().getHeaders().putAll(camelExchange.getIn().getHeaders());
> {code}
> Therefore, the second log endpoint within onException() block has it's camel
> exchange IN message been overwritten and replaced with OUT message from
> previous endpoint's although it is a message of NULL body.
