Subject [jira] Commented: (CAMEL-2224) Response received is of type java.lang.String instead of javax.ws.rs.core.Response
Date Wed, 25 Nov 2009 09:48:52 GMT

    [ https://issues.apache.org/activemq/browse/CAMEL-2224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=56085#action_56085
] 

Sergey Beryozkin commented on CAMEL-2224:
-----------------------------------------

So it should be an easy fix ?

The exception which is reported above is originated from the custom cxf jaxrs ResponseHandler...
As was discussed in the other JIRA which you closed yesterday, the CXF JAXRSOutInterceptor
was getting 
a response object being misrepresented as Object[]. So yesterday, 
Charles tried to to check what was inside that Object[] using a custom ResponseHandler. 

We thought that the object the IncidentService was returning (JAXRs Response in that specific
case) was wrapped 
as the first element of Object[], so the custom ResponseHandler tried to cast the first element
to Response...
