Sergey Beryozkin commented on CXF-5706:
---------------------------------------
> An option that could be interesting would be a smilar one to
> -noVoidForEmptyResponses, but instead of generating a Response type only the
> method that don't return a result (void) it will generate a Resposne for all
> methods.
I'll be working on such an option where it will be possible to apply it to
individual or all methods
Cheers, Sergey

> Key: CXF-5706
> URL: https://issues.apache.org/jira/browse/CXF-5706
> Project: CXF
> Issue Type: Bug
> Components: Tooling
> Affects Versions: 3.0.0-milestone2
> Environment: Java version "1.6.0_45"
> Windows 7 64 bit
> Reporter: Claude-Alain
>
> Regarding this subject, a fix has been done (CXF-3662) but I have some
> reasons to think that it has not been done in the right way.
> In the given example, there is one normal response (status code = 200) and
> one response which is an error (status code = 400). In that case the fix is
> doing the right thing, the first type is take into account and the error type
> can be managed by an exception mapper (from what I see in the documentation
> of RESTEasy and Jersey).
> But in the case we introduce another response like shown in the example just
> below:
> {code:xml}
> <method name="GET" id="getUserDefaults">
> <doc>Gets default user configuration values.</doc>
> <response status="200">
> <representation mediaType="application/xml"
> element="fmc:userDefaults" />
> </response>
> <response status="204">
> <representation mediaType="application/xml"
> element="fmc:noContent" />
> </response>
> <response status="400">
> <representation mediaType="application/xml"
> element="fmc:errorList" />
> </response>
> </method>
> {code}
> then the return type for the corresponding method in the generated interface
> will be "userDefaults". Since a Java method can only return an object of a
> given type then it will never be possible to return an object of type
> "noContent".
> So I think the only way to solve this case is to return a type
> "javax.ws.rs.core.Response".
> The only workaround I found is to remove the type type specified in the
> response to make sure that we always have a return type "Response".
