[Resteasy-users] problem using resteasy client proxy
|

Hi, I have created a client proxy using resteasy much like that described in the api-clients example in the resteasy package. I am using my client proxy to call the flickr api for some recent photos uploaded over there. However, for some reason, the flickr api always sends back charset="utf-8" in the content-type which screws with resteasy's ability to pick an appropriate message body reader. I get the following stacktrace javax.faces.el.EvaluationException: org.jboss.resteasy.client.ClientResponseFailure: Unable to find a MessageBodyReader of content-type text/xml;charset="utf-8" and type

javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:88) My question is this. What can I do to remove those unwarranted charset= directives from the content-type header to ensure that content negotiation works properly? I am thinking about all sorts of things such as filters which manipulate the client proxy response headers before the message reaches the messagebodyreader. Or perhaps there is a simpler solution? Please let me know. Thanks. |
