[jira] Commented: (CXF-2585) Already connected exception when using a proxy created with JAXRSClientFactory

["Sergey Beryozkin (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CXF-2585?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12791576#action_12791576 ] 

Sergey Beryozkin commented on CXF-2585:
---------------------------------------

it is a bug affecting a proxy based flavor only. 
The problem is that a proxy does not indicate to the transport-level HttpConduit that an empty POST (with no request body) is coming which is something that never occurs with SOAP proxies.

It will be fixed for soon to be released 2.2.6

Couple of workarounds.
1. Use WebClient :

Response r = WebClient.create(endpointAddress).query("param", "bob").post(null);
String s = (String)r.getEntity();

2. If you do prefer to use a proxy then for the empty POST be processed correctly, you can temporarily register a CXF out interceptor
with a proxy and set a "org.apache.cxf.post.empty" property on a message - let me know please if you'd like to try this option and I will post a code for the interceptor

thanks
