        at org.spotlight.DbAnnotationClient.request(DbAnnotationClient.java:42)

my code is :

public class DbSpotlightClient extends DbAnnotationClient {

//	private  String  API_URL    = "http://api.dbpedia-spotlight.org/en/annotate"; 
 private  String  API_URL    = "http://localhost:2222/rest";
	List<ResourceItem>resources;
	public List<ResourceItem> extract(String text)throws AnnotationException{
		String spotlightResponse=null;
		resources = null;
		try{
			    //client = HttpClientBuilder.create().build();
				client = new DefaultHttpClient();
		        HttpPost post = new HttpPost(API_URL);
		        List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
		        urlParameters.add(new BasicNameValuePair("text", text));
		        urlParameters.add(new BasicNameValuePair("confidence", "0.25"));
		        post.setEntity(new UrlEncodedFormEntity(urlParameters));
		        post.setHeader("Accept", "application/json");
		        spotlightResponse = request(post);
            Announce.message("spotlightResponse= ", spotlightResponse);
    	} 
		catch(UnsupportedEncodingException e){
	        throw new AnnotationException("Could not encode text.", e);
		} 
		assert spotlightResponse != null;
		
		try{
			AnnotationUnit annotationUnit = new Gson().fromJson(spotlightResponse.toString(), AnnotationUnit.class);
			
			resources = annotationUnit.getResources();
		}catch(Exception e){
			throw new AnnotationException("Received invalid response from DBpedia Spotlight API.");
		}
		return resources;
	}

	public static void main(String[] args) throws Exception {
		Announce.doing("Starting DBpediaSpotlightClient main ");
        DbSpotlightClient c = new DbSpotlightClient ();
        File input = new File("./abstract/test1.txt");
        File output = new File("./datasets/out/marsAnnotated.txt");
        c.evaluate(input, output);
        Announce.done();

	}
}

Noting that if i execute the following:

curl http://localhost:2222/rest/annotate \
  -H "Accept: text/xml" \
  --data-urlencode "text=Brazilian state-run giant oil company Petrobras signed a three-year technology and research cooperation agreement with oil service provider Halliburton." \
  --data "confidence=0" \
  --data "support=0"

We get the following:
