JAX-RS: HTTP Method URL matching on HEAD request

jsbournival Oct 26, 2009 2:38 PM

Hi, we have a problem with CXF rest impl. We are running CXF inside of servicemix4/OSGi.

Considering the resource class:

@Path("/myresource/...")

public class MyResource {

@GET

@Produces("application/atom+xml")

public Response getResource(...) { ... }

@HEAD

public Response headResource(...) { ... }

}

If I call my resource like this:

HEAD /myresource/... HTTP/1.1

I get the wonderful log entry that says: Resource class MyResource does not support HEAD http method, method getResource supporting GET http method will be invoked

Is there a known problem with HEAD? Is there something missing in our resource class?

Thanks for helping out!

JS.

Hi, sorry for a delay...

HEAD is supported and a number of JAXRS TCK tests test it, but I think what is happening here is that the first @GET method also matches HEAD requests, alongside with the method annotated with @HEAD...

For some reasons, the @GET method takes the priority, possibly because of the bug in CXF to do with the fact that the @GET method also has @Produces thus is is more 'specific'.

I think if you change the class as follows :

@Path("/myresource/...")
public class MyResource {

@HEAD
public Response headResource(...) { ... }

@GET
@Produces("application/atom+xml")
public Response getResource(...) { ... }

}

then it might work; I will also add a test and will get back to you

cheers, Sergey

Hi Sergei, is there a patch issued on this? I do not necessarily want to upgrade my CXF bundles at this point. i would rather instead recompile the same version and apply some patch. How can I grab the project source code? Does fuse have a svn repo, or is there a special branch/tag in CXF for fuses need?

Thank you,

JS.

(btw, I do not find the issue in JIRA. Was there one created?)
