如何解决JSON响应？

嗨，我正在做 REST Web 服务。当我请求 GET/POST 方法时，响应是 200 OK。但我想得到带有键、值的响应。所以我这样写：

    @GET
    @Produces("application/json")
    public Response getContainer(@Context HttpHeaders headers){

        mongoDAOImpl impl=new mongoDAOImpl();
        Mongo mongo=impl.getConnection("127.0.0.1","27017");
        DB db=impl.getDataBase(mongo,"public");
        DBCollection coll=impl.getColl(db,"public");
        mongoDTO dto=new mongoDTO();


    try{
        DBCursor dbcur=impl.findAllRecords(coll);
        DBObject o;
        while(dbcur.hasNext()){
            o=dbcur.next();

        }
        if(dbcur==null){
            return Response.status(Response.Status.NOT_FOUND).build();
        }else{
            String respStr=dto.toJson(false);
         return Response.ok(respStr).header("Specification-version", "1.0").build();
          }
    }
        catch(Exception ex){
                ex.printStackTrace();
        return Response.status(Response.Status.NOT_FOUND).tag("Container Read Error : " + ex.toString()).build();
     }
    }

但我得到的结果是

GET /web/jersey/resources/cloud/juniarto HTTP/1.1 用户代理：curl/7.21.0 (i686-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.18 主机：本地主机：26235 接受：*/* HTTP/1.1 200 正常 X-Powered-By：Servlet/3.0 服务器：GlassFish 服务器开源版3.0.1 规范版本：1.0 内容类型：application/json 传输编码：分块日期：2011 年 4 月 6 日星期三 00:56:48 GMT 与主机 localhost 的连接 #0 保持完好关闭连接 #0 错误：org.codehaus.jackson.JsonGenerationException：无法写入字段名称，需要一个值

有什么建议吗？

Hi,
I am doing REST web service.
When I request the GET/ POST method, the response is 200 OK.
But I want to get the response with key,value. so i write like this:

    @GET
    @Produces("application/json")
    public Response getContainer(@Context HttpHeaders headers){

        mongoDAOImpl impl=new mongoDAOImpl();
        Mongo mongo=impl.getConnection("127.0.0.1","27017");
        DB db=impl.getDataBase(mongo,"public");
        DBCollection coll=impl.getColl(db,"public");
        mongoDTO dto=new mongoDTO();


    try{
        DBCursor dbcur=impl.findAllRecords(coll);
        DBObject o;
        while(dbcur.hasNext()){
            o=dbcur.next();

        }
        if(dbcur==null){
            return Response.status(Response.Status.NOT_FOUND).build();
        }else{
            String respStr=dto.toJson(false);
         return Response.ok(respStr).header("Specification-version", "1.0").build();
          }
    }
        catch(Exception ex){
                ex.printStackTrace();
        return Response.status(Response.Status.NOT_FOUND).tag("Container Read Error : " + ex.toString()).build();
     }
    }

But I got the result is

GET /web/jersey/resources/cloud/juniarto HTTP/1.1 User-Agent: curl/7.21.0 (i686-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.18 Host: localhost:26235 Accept: */* HTTP/1.1 200 OK X-Powered-By: Servlet/3.0 Server: GlassFish Server Open Source Edition 3.0.1 Specification-version: 1.0 Content-Type: application/json Transfer-Encoding: chunked Date: Wed, 06 Apr 2011 00:56:48 GMT Connection #0 to host localhost left intact Closing connection #0 Error:org.codehaus.jackson.JsonGenerationException: Can not write a field name, expecting a values

Any suggestion?
