Java认证:Java实现点在线添加

 Java认证:Java实现点在线添加,内容如下:
  public void addPoint(MapEvent event){
  AGSLocalMapResource res = (AGSLocalMapResource)this.webContext.getResources()。get(“ags0”);
  try{
  // 建立一个工作空间工厂对象,并设置它的参数信息。
  SdeWorkspaceFactory sdewf = (SdeWorkspaceFactory)res.getServerContext()。createObject(SdeWorkspaceFactory.getClsid());
  PropertySet pset = (PropertySet)res.getServerContext()。createObject(PropertySet.getClsid());
  pset.setProperty(“SERVER”, “gxk”);// 服务器名称
  pset.setProperty(“INSTANCE”, “5151”);// 实例名
  pset.setProperty(“USER”, “sa”); // SDE数据表空间的用户名
  pset.setProperty(“PASSWORD”, “sa”);// 密码
  pset.setProperty(“VERSION”, “DBO.gxk”);// SDE数据的版本
  Workspace iws =(Workspace) sdewf.open(pset, 0);
  WebPoint screenPoint = (WebPoint)event.getWebGeometry();
  WebMap mapctrl = event.getWebContext()。getWebMap();
  WebPoint mappnt =WebPoint.toMapPoint(screenPoint, mapctrl.getCurrentExtent(), (int)mapctrl.getWidth(), (int)mapctrl.getHeight());
  Geometry soapgeo=AGSUtil.toAGSGeometry(mappnt);
  String soapString = com.esri.adf.web.ags.util.AGSUtil.serializeStub(soapgeo);
  soapString = soapString.replaceAll(“xsi:type=\”soapenc:Array\“”, “”);
  IPoint mypoint = (IPoint)AGSUtil.deserializeArcObject(soapString, res.getServerContext());
  IWorkspaceEdit wse = (IWorkspaceEdit)iws;
  wse.startEditing(false);
  wse.startEditOperation();
  IFeatureClass featureclass = iws.openFeatureClass(“sde.DBO.Respt”);
  IFeature feature = featureclass.createFeature();
  feature.setShapeByRef((IGeometry)mypoint);
  feature.setValue(feature.getFields()。findField(“NAME”), “kkk”);
  feature.store();
  wse.stopEditOperation();
  wse.stopEditing(true);
  this.webContext.refresh();
  }catch(Exception e){
  e.printStackTrace();
  }
  }
  刷新地图后不能显示新加入的数据的原因是:由于在开始编辑时新打开了一个工作空间,该工作空间并不是浏览器中看到地图所在的工作空间。
