> CXF Failover using JAXRS prevents header retrieval from

> --------------------------------------------------------------------------------

> Key: CXF-6657
> URL: https://issues.apache.org/jira/browse/CXF-6657
> Project: CXF
> Issue Type: Bug
> Components: clusting, JAX-RS, Transports
> Affects Versions: 2.7.17
> Environment: JAXRS Client 2.7.17 with Sequential Failover and a
> ResponseExceptionMapper.
> Reporter: Florian Léger
> Attachments:
> Failover-make-failover-work-without-forcing-org.apac.patch

>
> Our custom ResponseExceptionMapper is designed to transform responses with
> status code 400 into client code exceptions by retrieving custom header
> properties.
> This works as long as the failover feature is not enabled, were would want
> the failover code to be triggered only in case of support not available
> errors but let through other status codes
> When using the FailoverFeature and even when setting the
> supportNotAvailableErrorsOnly property of the FailoverTargetSelector to true,
> an HttpException is raised in the handleResponseInternal method of
> HTTPConduit which prevents the headers from being updated in the input
> message.
> This is due to the fact that the FailoverTargetSelector clears the
> org.apache.cxf.transport.no_io_exceptions flag set by JAXRS.
> The attached patch make the FailoverTargetSelector clears the
> org.apache.cxf.transport.no_io_exceptions flag only when
> supportNotAvailableErrorsOnly is false. It also modifies
> HTTPConduit.handleResponseInternal to set
> org.apache.cxf.transport.service_not_available even if no IOExceptions should
> be thrown so that the failover code could catch such cases. Finally, it also
> make the preProcessResult method of jaxrs AbstractClient complete the conduit
> selector if org.apache.cxf.transport.service_not_available is true in case of
> failover.
