this one helps. you get this %7B%22ID%22:%22324%22%7D because the value {"ID":"324"} got URL-Enecoded when the request was sent.
you need to URL-Decode that and you will get your value.
code :
String jsonParam = URLDecoder.decode(paramVal, "UTF8");

it fixes the issue The eventual workaround was the code hack described in https://stackoverflow.com/a/19230016/449347
See the bug raised at https://github.com/restlet/restlet-framework-java/issues/785

wish helps you Don't worry! There is no silly question ;-)
Sure, you can use Restlet with only JavaSE for the server side. You can define a Restlet server within a standalone Java application. This can be done using the class Component. After having instantiated it, you can add a server to it. Following code describes this:
code :
public static void main(String[] args) {
    Component component = new Component();
    component.getServers().add(Protocol.HTTP, 8080);
component.getDefaultHost().attach(new SampleApplication());
public class SampleApplication extends Application {
    public Restlet createInboundRoot() {
        Router router = new Router(getContext());

        router.attach("/myresource", MyServerResource.class);


        return router;
String rootUri = "file:///(...)/static-content";
Directory directory = new Directory(getContext(), rootUri);
router.attach("/static/", directory);
public class SampleApplication extends Application {
    private Configuration configuration;

    public static Configuration configureFreeMarker(Context context) {
        Configuration configuration = new Configuration();
        ClassTemplateLoader loader = new ClassTemplateLoader(
        // configuration.setCacheStorage(new StrongCacheStorage());
        return configuration;

    public Configuration getConfiguration() {
        return configuration;
private SampleApplication getSampleApplication() {
    return (SampleApplication)getApplication();

private Representation toRepresentation(Map<String, Object> map,
    String templateName, MediaType mediaType) {
    return new TemplateRepresentation(templateName,
        getSampleApplication().getConfiguration(), map, mediaType);

public Representation getHtml() {
    Map<String, Object> model = new HashMap<String, Object>();

    model.put("titre", "my title");
    model.put("users", getUsers());

    return toRepresentation(model,
        "myTemplate", MediaType.TEXT_HTML);
        <#list users as user>
        <li>${user.lastName} ${user.firstName}</li>
How to diagnose "org.restlet.data.Parameter cannot be cast to org.restlet.data.Header" error in Restlet 2.3.5?

hope this fix your issue This could be caused when trying to add custom headers in Restlet. When initializing the corresponding map, you would use a map (Series in Restlet) of Parameter instead of Header...
You can use something like that:
code :
Series<Header> responseHeaders = (Series<Header>) 
if (responseHeaders == null) { 
    responseHeaders = new Series(Header.class); 
            HeaderConstants.ATTRIBUTE_HEADERS, responseHeaders); 
responseHeaders.add(new Header("X-MyHeader", "value"));

may help you . Using just 1 JAR jse-x.y.z/lib/org.restlet.jar, you could construct JSON by hand at the client side for simple requests:
