Hi,

I've been struggling with getting Hessian (4.0.3) to work on a device running creme 4.12 (arm architecture).
I'm using netbeans 6.8 and the code's working if I'm running it by using the emulator.

When I run the same test program on the remote vm (the connected device), it throws an exception.

Client code:

 String url = "http://192.168.1.7:8080/WebApplication1/BasicService";

            HttpConnection c = (HttpConnection) Connector.open(url);
            c.setRequestMethod(HttpConnection.POST);
            c.setRequestProperty("content-type","x-application/hessian");
            
            OutputStream os = c.openOutputStream();
            MicroHessianOutput out = new MicroHessianOutput(os);

            out.startCall("hello");
            out.writeString("3552AGNH");
            out.completeCall();
            //os.flush();

            InputStream is = c.openInputStream();

            MicroHessianInput in = new MicroHessianInput(is);
            in.startReply();
            String result = in.readString();
            JOptionPane.showMessageDialog(this, result);
            in.completeReply();

Servlet code:

public class BasicService extends HessianServlet
{
    public String hello(String artCode)
    {
        return "result: " + artCode;
    }
}

Exception thrown when the code is run in the remote VM:

Does anyone know how I can resolve this issue?

Looking forward to your replies.
