arcgis sample代码之SOE示例代码PageLayout REST Server Object Extension的源码分析(Java)

为什么10.2里面没有pagelayout的代码了。。

10.2版本的arcobjects for java sdk自带例子

                 10.0版本的arcobjects for java sdk自带例子

IMapServerLayout......这个类还是在的

在src/arcgissample.soe包下 有 PageLayoutImpl.java 和 PageLayoutSOE.java

其中还有一个 rest 的java客户端，这个是单独运行的，和上面两个没啥关系。上面两个文件发布成 jar文件，放到java/lib/ext文件夹下面后部署SOE成功，并且添加到地图服务的 功能  上就可以使用了。比如http://localhost:8399/arcgis/rest/services/portland/MapServer/exts/PageLayoutSOE就是portland的地图服务下面的扩展功能 SOE 是 PageLayoutSOE 了。其实这个SOE可以放到任何一个地图服务的扩展功能当中。

arcgis自带的eclipse无法打开。。。从网上自己下的eclipse3.3，具体的安装和导入arcobjects：链接

PageLayoutRESTClient.java

其实核心函数只有100行不到

如何把这段代码移植到C#.NET。。。
