[Resteasy-users] Help with unmarshalling message body into Java object

[David H. <dav...@gm...>]

I am stumped by this one and would appreciate any help. I am having trouble
parsing the response body back into a Java object.

The relevant piece of code looks like this:
       ClientRequest request = new ClientRequest(sdURL);
        request.body("application/xml", xml);

        try {
            ClientResponse<SdErrorMessageXml> response = request.post();

            if( response.getResponseStatus() != Response.Status.NO_CONTENT )
{
                System.out.println("service returned a
'"+response.getResponseStatus()+"' response");
                SdErrorMessageXml error =
response.getEntity(SdErrorMessageXml.class);
                System.out.println("service desk error: "+error.getText());
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

The SdErrorMessageXml was generated from and XSD using xjc.

When I attempt to use the getEntity() method, I get the following:
service returned a 'Not Modified' response

Resteasy 1.2.1, jaxrs 1.2.1, jaxb-2.1

I have tried a number of ideas but none of them have worked out.
If you have any suggestions, I would be grateful if you sent them to me.

Thanks
