1.发布地图服务。
2.添加样式引用:
link rel="stylesheet" type="text/css" href="http://serverapi.arcgisonline.com/jsapi/arcgis/1.5/js/dojo/dijit/themes/tundra/tundra.css">
此样式用来定义body的样式。引用后就可以在body中利用class=“tundra”
link标签的用法具体见:http://www.w3school.com.cn/tags/tag_link.asp
3.添加js引用,此引用必须有,javascript API就是依此包完成GIS功能的。
引用地址为:<script type="text/javascript" src="http://serverapi.arcgisonline.com/jsapi/arcgis/?v=1.5"></script>
4.添加层div,用来显示地图:
<div id="map" style="width:900px; height:600px; border:1px solid #000;"></div>
5.添加JavaScript初始化地图,并加载本地图层。
function init() {
var map = new esri.Map("map"); //注册map控件
var imageParameters = new esri.layers.ImageParameters();
imageParameters.format = "png24"; //set the image type to PNG24, note default is PNG8.
//Takes a URL to a non cached map service.
var dynamicMapServiceLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Population_World/MapServer", {"opacity":0.5, "imageParameters":imageParameters});
map.addLayer(dynamicMapServiceLayer);
}
本例全部代码如下
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

Creates a map and adds an ArcGISDynamicMapServiceLayer.<br />
Map navigation using mouse:
<ul>
<li>Drag to pan</li>
<li>SHIFT + Click to recenter</li>
<li>SHIFT + Drag to zoom in</li>
<li>SHIFT + CTRL + Drag to zoom out</li>
<li>Mouse Scroll Forward to zoom in</li>
<li>Mouse Scroll Backward to zoom out</li>
<li>Use Arrow keys to pan</li>
<li>+ key to zoom in a level</li>
<li>- key to zoom out a level</li>
<li>Double Click to Center and Zoom in</li>
</ul>
