Reservieren Ausnahme für servlet-Jersey-REST-Dienst Fehler

Bin ich wieder-Kodierung eines webservice, die ich bereits erstellt, so dass ich eine "how-to" mit git für die anderen Mitglieder meiner Gruppe, wer übernimmt das Projekt.

Diese Zeit herum begann ich erhalte eine Fehlermeldung, wenn Sie versuchen, um meine webservice-und ich kann nicht scheinen, um das problem zu finden, da der code sieht genauso aus wie das, was ich schon vorher codiert (ein code, der funktioniert).

Ich bin mit apache tomcat und Jersey mit JSON.

Hier ist der Fehler:

Hier ist eine Klasse, die verwendet die @Path-annotation:

//url path for class it's methods/chemin url pour la classe et ses methodes
@Path ("/v1/inventory") 
public class V1__inventory
{


@GET //url ending in only /v1/inventory /chemin terminé par /v1/inventory
@Produces(MediaType.APPLICATION_JSON) 
public Response errorIfNoQueryParamSpecified() throws Exception
{
        return Response
                .status(400) //bad request
                .entity("Error: Please specify extension and parameter for this search.") 
                .build();
}

/**
 * Method that returns materials filter by material name
 * @param material name
 * @return Response

 */

@Path("/{material_label}") 
@GET
@Produces(MediaType.APPLICATION_JSON)
public Response returnMaterial(@PathParam("material_label") String material) throws Exception
{

    material = URLDecoder.decode(material, "UTF-8"); //decode URL param
    String returnString = null;
    JSONArray json;

    try
    {   

        json = LabTab_MySQLQuerys 
                .getMaterialsByName(material);

        //if there are no results to the query
        if(json.length() == 0) 
            throw new CustomException("No results returned");
        else //otherwise return results
            returnString = json.toString();

    }
    catch(CustomException e)
    {
        return Response
                .status(204)
                .entity(e.getMessage())
                .build();
    }
    catch (Exception e)
    {
        e.printStackTrace();
        return Response
                .status(500) //internal server error
                .entity("Server was not able to process your request")
                .build();
    }

    return Response
            .ok(returnString)

Ich habe suchen und Lesen die gleichen Artikel immer und immer wieder für 3 Tage jetzt und ich habe noch eine Lösung zu finden, das löst mein Fehler.

Alle Hilfe ist willkommen
