JAXRS / CXF why is this simple post example not working

Question

I know my client works as I post to another website and it all works. I changed the client to post to url http://localhost:9000/enrollment/enroll and ran the following server...

@Path("/enrollment")
public class MockHpsRestApi {

    private static final Logger log = LoggerFactory.getLogger(MockHpsRestApi.class);

    public static void main(final String[] args) throws InterruptedException,
            IOException, MuleException {
        log.info("starting the server");
        JAXRSServerFactoryBean sf = new JAXRSServerFactoryBean();
        sf.setResourceClasses(MockHpsRestApi.class);
        sf.setResourceProvider(MockHpsRestApi.class, new SingletonResourceProvider(new MockHpsRestApi()));

        sf.setAddress("http://0.0.0.0:9000/");

        sf.create();
    }

    @POST
    @Path("/enroll")
    @Consumes("application/xml")
    public String enrollment(MultipartBody body) throws IOException {
        log.info("received request="+body);
        Attachment att = body.getRootAttachment();
        ByteArrayOutputStream str = new ByteArrayOutputStream(100);
        InputStream in = att.getDataHandler().getInputStream();
        try {
            IOUtils.copy(in, str);

            log.info("body payload received="+str);
            String xml = "success";
            return xml;
        } finally {
            IOUtils.closeQuietly(in);
            IOUtils.closeQuietly(str);
        }
    }
}

My logs though say this when it receives the request...

Why isn't this working?

hmmm, turning up the log levels, is this some kind of bug in CXF, though that would mean no one is really doing basic posts, so that doesn't seem right....(again, my client posts fine to another service today).

Answer 1

After debugging the code, it turns out you can use the following types as parameters to the method above.

• Source
• XMLSource
• Document
• byte[]
• InputStream

I ended up using InputStream.

Answer 2

When using @POST and @Consumes("application/xml"), it's normal for the (single un-annotated) argument type on the method to be a JAXB-annotated class that CXF will deserialize the XML into before handing it to you. Is there a particular reason for not going that well-travelled route?
