arcgis server 服务调用不显示

（纯新手代码都是复制的）最近有需求要做web的地图，用arcgis发了服务，在服务管理页面ArcGIS JavaScript 可以预览，代码调用之后不显示发布的地图服务，然后在网上下载了中国的行政区地图，行政区的地图发布服务之后调用可以显示出来，尝试过重新切片，要把切片切到能显示的级别，切片有几十万TB，自己发布的服务地图是室内地图，只有一栋建筑大小，现在该怎么设置，才能让我的地图显示出来这个是需要设置地图显示范围的代码，

         "esri/geometry/Extent",
         "esri/SpatialReference"], function(
            Map,
            ArcGISDynamicMapServiceLayer,
            ArcGISTiledMapServiceLayer,
            Extent,
            SpatialReference
      ) {
         var extent = new Extent(71.010089,21.288148,135.768574,54.399626, new SpatialReference({ wkid:4326 }));
         var map = new Map("map", {
            //center: [116.403119,39.915599],
            //zoom:2,
            extent:extent,
            basemap: "streets" //satellite、streets、oceans
         });
         //调用切片地图服务
         var TiledLayer=new esri.layers.ArcGISTiledMapServiceLayer('url');
         map.addLayer(TiledLayer);
      });
</script>
</head>
<body>
<div id='map'>

</div>

</html>.

var extent = new Extent(71.010089,21.288148,135.768574,54.399626, new SpatialReference({ wkid:4326 }));
这一串代码里坐标是怎么获取的，从哪里转换来的，还有显示范围应该是怎么设置。。。。

这个是另外一个加载地图的代码
