if (requestContentType == null) {

> Key: CXF-1730
> URL: https://issues.apache.org/jira/browse/CXF-1730
> Project: CXF
> Issue Type: Bug
> Components: REST
> Affects Versions: 2.1.2
> Environment: Windows XP, jdk1.6, Apache Tomcat 6.0.16
> Reporter: Frank Ittermann
>
> Hello again
> i' ve used an implementation of RequestHandler to perform authentication
> stuff. So
> if the Authentication failed a RuntimeException is thrown. I've also wrote a
> ExceptionMapper implementation to transform occurred Exception into Http
> Status codes. If the RuntimeException from the Authentication was thrown than
> this is translated to an HTTP 403 status code.
> But this Http status code is not send as response. This sends a 200 status
> code. After a time of debugging i found the code that is responsible for
> that. The processResponse method of the
> org.apache.cxf.jaxrs.interceptor.JAXRSOutInterceptor work not correct is
> guess. Because code with the following code block this methods ends.
> OperationResourceInfo operation =
> (OperationResourceInfo)exchange.get(OperationResourceInfo.class
> .getName());
> if (operation == null) {
> return;
> }
> because the operation variable is null. The code after this is responsible to
> but the Response from the ExceptionMapper class into the message object so
> that i received a 403 http status code.
> I've searched the code again and i found the code block how put the
> OperationResourceInfo into the Exchange object. That is done by the
> processRequest method of the
> org.apache.cxf.jaxrs.interceptor.JAXRSInInterceptor class. But before the
> OperationResourceInfo object is putted in the registered ResourceHandler are
> called see the code block below.
> for (ProviderInfo<RequestHandler> sh : shs) {
> Response response = sh.getProvider().handleRequest(message,
> resource);
> if (response != null) {
> message.getExchange().put(Response.class, response);
> return;
> }
> }
> I guess the code how put in the OperationresourceInfo object could be
> performed before the RequestHandlers are called maybe?
> Or it's forbidden to throw a Runtimeexception inside the RequestHandler ?
> I've also tried to return an Response object from the RequestHandler but the
> effect was the same it never arrives the client. It received also the
> Response object with http code 200.
> The CXF framework is great and very flexible good work. The opportunities to
> register own code is very great.
> Good work.
