CXF 3.0.7 JAXRS POST read body

  Hi everybody,


I am currently refactoring a REST application whose implementation is based on a subclass of javax.servlet.http.HttpServlet and thus is using javax.servlet.http.HttpServletRequest and javax.servlet.http.HttpServletResponse quite extensively to use CXF and JAXRS.
The refactored version of the application extends org.apache.cxf.transport.servlet.CXFNonSpringServlet and is using a service class which defines methods using the javax.ws.rs.core.Context annotation to obtain HttpServletRequest objets, e.g.

                @POST
                public void doPost(@Context HttpServletRequest request, @Context HttpServletResponse response)  {
                               ...
                }

Now, for GET operations this works as expected. When I try to read the body of a POST request using the javax.servlet.ServletRequest.getInputStream(), the returned InputStream ist empty.
According to JAX-RS spec, I guess I could extend my method to something like

                @POST
                public void doPost(@Context HttpServletRequest request, @Context HttpServletResponse response, String body)  {
                               ...
                }

in order to get the body. However, I'd like to avoid that because I don't want to change the existing application implementation too much.
So  I have 2 questions:

1.       Why does javax.servlet.ServletRequest.getInputStream() return an InputStream that contains no data whe I using CXF? This work fine in the old style of the application.

2.       What can I do to be able to read the body that way using CXF?


Viele Grüße,
Julien

AW: CXF 3.0.7 JAXRS POST read body

Posted by Julien Charon <Ju...@avitech.aero>.
  Hi,


Thanks Sergey. You're right, I should make use of the JAX-RS mechanisms. But because I already ran into some problems, I am a little bit concerned facing further more severe problems especially when it comes to chunking etc. So I'd like to be able to run both variants of our application in parallel or to be able to switch back to the old variant at any time. 


Best regards,
 
Julien

Hi

Perhaps it is supposed to work with JAX-RS, so I've fixed it as part of
https://issues.apache.org/jira/browse/CXF-6709

I'd still recommend you to avoid dealing with Servlet request/response directly - one of the main ideas of JAX-RS was to provide a simpler/alternative mechanism.

Thanks, Sergey
