Hi again
I have a question about returning responses to HTTP requests in the context of
a RESTful web service.
This is my method declaration in the WADL:
<method id="saveA" name="PUT">
<request>
<representation mediaType="application/xml" element="ns1:A" />
</request>
<response status="200">
<param name="header1" style="header" type="xsd:string" />
</response>
</method>
After generating the code, I get the following method signature:
public void saveA(AType atype);
Does the method is generated as expected ? (referring to your other
email re PUT method)
If the PUT operation performed well, I would like to return an HTTP response
with status code 200 and an HTTP header containing a certain value. This is
indicated in the WADL, but I don't see anything in the code. Since the method
saveA doesn't return anything, where is the right place to customize the
response (i.e. setting the desired status code and header)?
Typically a Response would be returned from the method in such cases,
built like this:
Response.status(myStatus).header(key, value).build();
I wonder if the generator should generate 'Response' by default in such
cases, where no response representation is expected...Or this should be
configurable at least, I'll look into it.
In meantime, add ResponseHandler filter (on CXF 2.6.x) or
ContainerResponseFilter (on CXF 2.7.0) and add a required header from
there...
Also, what if for a given request, different responses may be returned
according to how the operation performed? Should I add multiple responses in
the method element (in the WADL)?
At the moment the simplest thing to do is to
<response status="200 400 401">
etc
Creating multiple responses is also valid but as far as the code
generation is concerned, it won't make any difference, given that at the
code level the relevant exceptions are all runtime ones. However, it can
be better for the reader of WADL because you can attach specific
descriptions to different response elements...
Cheers, Sergey
Thanks,
