-------------------------------------------------------------------------------
Key: CXF-4248
URL: https://issues.apache.org/jira/browse/CXF-4248
Project: CXF
Issue Type: Improvement
Reporter: Andrei Shakirin
Priority: Minor
Attachments: HTTPConduit.patch
Hi,
Test case: Web service provides oneWay operation (SoapUI mock), but sends
non-empty SOAP response back
Expected: response will be ignored
Actual: DocLiteralInInterceptor throws NPE
Caused by: java.lang.NullPointerException

Fix proposal: I have discovered that there are some cases when oneWay response
can be proceeded. Regarding Basic Profile 1.1:
R2714 For one-way operations, an HTTP Response MESSAGE MAY contain an envelope.
One-way operations typically do not produce SOAP responses. However, some
INSTANCEs may choose to communicate infrastructure-related faults (e.g.
MustUnderstand, VersionMismatch) in the HTTP Response message.
In addition to this, the use of some protocol extensions (e.g.
WS-ReliableMessaging) may create the possibility for non-empty responses to
one-way messages. For these reasons the Basic Profile 1.1 requirement that the
HTTP Response message not contain a SOAP envelope has been relaxed.
I would propose to process oneWay response only in following cases:
A) if RM is active (check RMMessageConstants.RM_PROPERTIES_OUTBOUND,
RMMessageConstants.RM_PROPERTIES_INBOUND)
B) if user activate it with org.apache.cxf.transport.processOneWayResponse
property on consumer
In other case oneWay response will be ignored by client.
Patch is attached.
Regards,
Andrei.
