PUT and POST not working from J2SE platform (RESTLET Version 3.0-M1)

I'm working on a project with GWT and J2SE clients. The GWT part is working great, but now there are problems with the J2SE client;

"The server understands the content type of the request entity and the syntax of the request entity is correct but was unable to process the contained instructions"

"The serialized representation must have this media type: application/x-java-serialized-object or this one: application/x-java-serialized-object+xml"

ERROR MESSAGE

This code was working some months/versions ago... Both PUT and POST produce this error while GET is working. Whats wrong here?

Here's a really simple test case

// Shared Interface 

public interface J2SeClientServerResourceInt
{
   @Post("json")
   public J2seStatusDto postJ2seStatus(J2seStatusDto pJ2seStatusDto);
}

// Java Bean

  public class J2seStatusDto implements Serializable
    {
        private static final long serialVersionUID = 6901448809350740172L;

        private String mTest;

        public J2seStatusDto()
        {
        }

        public J2seStatusDto(String pTest)
        {
            setTest(pTest); 
        }

        public String getTest()
        {
            return mTest;
        }

        public void setTest(String pTest)
        {
            mTest = pTest;
        }
    }

// Server 

public class J2seServerResource extends ClaireServerResource implements J2SeServerResourceInt
{
    @Override
    public J2seStatusDto postJ2seStatusDto(J2seStatusDto pJ2seStatusDto)
    {
        return pJ2seStatusDto;
    }
}

// J2SE Client 

public class ClaireJsSeTestClient
{
    public static void main(String[] args)
    {
        Reference lReference = new Reference("http://localhost:8888//rest/j2se");
        ClientResource lClientResource = new ClientResource(lReference);
        lClientResource.accept(MediaType.APPLICATION_JSON);
        J2SeServerResourceInt lJ2SeServerResource = lClientResource.wrap(J2SeServerResourceInt.class);
        J2seStatusDto lJ2seStatusDto = new J2seStatusDto("TEST");
        J2seStatusDto lJ2seResultDto = lJ2SeServerResource.postJ2seStatusDto(lJ2seStatusDto);
    }
}

Solution

  • Thierry Boileau fixed our problem (mistake);

    https://github.com/restlet/restlet-framework-java/issues/1029#issuecomment-76212062

    Due to the constraints of the GAE platform (there is no support of chunked encoding) you have to specify that the request entity is buffered first;

    cr.setRequestEntityBuffering(true);

    Thanks for the great support at restlet.com
