Restlet 내부 500 오류

Question

GAE 호스트 서비스 용 jUnit 테스트 케이스를 구축 중이며 그 중 하나의 메소드에 문제가 있습니다.

public interface BasketItemResource { 

    @Delete 
    public void removeBasketItem(String id); 

    @Get 
    public Representation listBasketItems(); 

    @Put 
    public void addBasketItems(Representation items); 
} 

여기 내 테스트 케이스이다 : 여기

는 자원 인터페이스입니다

@Test 
public void testListItems() { 

    Gson gson = new Gson(); 
    List<BasketItem> items = null; 

    JsonRepresentation jRep = null; 
    Type collectionType = new TypeToken<List<BasketItem>>(){}.getType(); 
    try { 
     jRep = new JsonRepresentation(resource.listBasketItems()); 
     items = gson.fromJson(jRep.getJsonArray().toString(), collectionType); 
    } catch (JsonSyntaxException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (JSONException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 

    assertEquals(items.size(), 5); 
} 

@Test 
public void testAddItem() { 
    Gson gson = new Gson(); 

    BasketItem b = new BasketItem(); 
    b.basketItemID = 123; 
    b.brandName = "Pepsi"; 
    b.description = "Cola Beverage"; 
    b.upc = "123123123"; 

    List<BasketItem> items = new ArrayList<BasketItem>(); 
    items.add(b); 

    JsonRepresentation jRep = null; 
    try { 
     jRep = new JsonRepresentation(new JSONArray(gson.toJson(items))); 
    } catch (JSONException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 

    resource.addBasketItems(jRep); 

    } 

많은 ListItems 테스트가 잘 실행하지만 난 testAddItems를() 내가 처음이 경고를 실행할 때 : 이 스택 하였다

, 클래스 org.restlet.client.ext.json.JsonConverter 찾을 수 없습니다. jyit 테스트를 실행할 때 클래스 org.restlet.client.ext.json.JsonConverter을 포함하는 jar 파일이 클래스 경로에 있는지 확인하십시오. 아마도 프로젝트의 /WEB-INF/lib 폴더를 클래스 경로에 추가하면 문제가 해결 될 것입니다.
