Subject [jira] [Commented] (CXF-5745) CXF Failover feature does not return to primary URL. It returns to first in failover urls.
Date Wed, 21 May 2014 11:03:38 GMT

    [ https://issues.apache.org/jira/browse/CXF-5745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14004574#comment-14004574

Jan Zanda commented on CXF-5745:
--------------------------------

Hi Sergey, 

that is a possible workaround, but it is not a clean solution. You cannot instantiate a consumer
without specifying the primary URL, so you would have to duplicate the same url to the list
of failover urls. That seems like bad pattern to me. 

I will have to implement some of the solutions Xilai wrote about. 

I still hope for a response if this is a bug or feature, though.

>             Project: CXF
>          Issue Type: Bug
>          Components: JAX-WS Runtime
>    Affects Versions: 2.7.5
>            Reporter: Jan Zanda
>            Priority: Minor

> I have a WS consumer, which uses one primary URL and up to 8 failover urls. 
> The consumer is created this way (see also comments in code):
> {noformat}
> JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
> factory.setServiceClass(SomeClientClass.class);
> factory.setAddress(primaryUrl); // this is http://primaryhost/service
> factory.setFeatures(getFailoverFeatures());
> List<AbstractFeature> getFailoverFeatures() {
>   FailoverFeature feature = new FailoverFeature();
>   SequentialStrategy strategy = new SequentialStrategy(); 
>   strategy.setAlternateAddresses(failoverUrls); //failoverUrls is a List of urls.
>   // something like {'http://failoverOne/service', 'http://failoverTwo/service'}
>   feature.setStrategy(strategy);
>   List<AbstractFeature> features = new ArrayList<AbstractFeature>();
>   features.add(feature);
>   return features;
> }
> {noformat}
> However, when application run out of failover URLs, it will write to log this:
> {noformat}
> 2014-05-16 09:00:03,473 WARN  [AbstractStaticFailoverStrategy] no alternate targets remain
=> giving up on failover
> 2014-05-16 09:00:03,473 INFO  [FailoverTargetSelector] reverted to original address http://failoverOne/service
> {noformat}
> Is there a way how to tell the failover feature to rotate ALL of the urls, primary URL
included?
> Thanks.
