@Override
protected void writeRemoteInvocationResult(HttpExchange exchange, RemoteInvocationResult result,
        OutputStream os) throws IOException {
    Object content = result.getException();
    if (content == null)
        content = result.getValue();/*from  w w  w.jav  a  2  s  . c o  m*/
    String type = content == null ? null : content.getClass().getName();

    JsonGenerator generator = factory.createJsonGenerator(os);

    generator.writeStartObject();
    generator.writeFieldName("type");
    generator.writeString(type);
    generator.writeFieldName("content");
