内容摘要
使用ArcGIS Server java ADF开发，如果需要空间关系查询，可以有两种办法，
一种是通过com.esri.arcgisws.SpatialFilter这个包来实现，是一种SOAP的方式，
另外一种是使用传统的AO的方式实现：com.esri.arcgis.geodatabase.SpatialFilter注意两个包的命名一样，很容易混淆。
过程描述
第一种方式的代码如下：

   MapLayerInfo layerInfos[] = functionality.getLayerInfos(); 
   for(int layerIndex=0;layerIndex<layerInfos.length;layerIndex++){
    MapLayerInfo mapLayerInfo = (MapLayerInfo) layerInfos[layerIndex]; 
    Field[] fields=mapLayerInfo.getFields().getFieldArray();
    RecordSet recordSet = mapServer.queryFeatureData(mapName, layerIndex, filter); 
    ...
    }

第二种方式代码如下：

  1. SpatialFilter spatialFilter= (SpatialFilter)serverContext.createObject(SpatialFilter.getClsid());   
  2.      
  3.   WebPolygon wPgon=(WebPolygon)event.getWebGeometry().toMapGeometry(event.getWebContext().getWebMap());   
  4.   GraphicElement ge =  new  GraphicElement();   
  5.   ge.setGeometry(wPgon);   
  6.    ge.setSymbol( this .getWebContext().getWebQuery().getPolygonGraphicSymbol());   
  7.     this .getWebContext().getWebGraphics().addGraphics(ge);   
  8.      
  9.    Geometry geom = AGSUtil.toAGSGeometry(wPgon);   
  10.    com.esri.arcgisws.PolygonN pgonN = (com.esri.arcgisws.PolygonN)geom;   
  11.    Polygon aoPgon = (Polygon)AGSUtil.createArcObjectFromStub(pgonN, serverContext);   
  12.       
  13.     for ( int  layerIndex= 0 ;layerIndex<pMap.getLayerCount();layerIndex++){   
  14.     ILayer layer=pMap.getLayer(layerIndex);   
  15.     FeatureLayer featureLayer=(FeatureLayer)layer;   
  16.     IFeatureClass featureClass=featureLayer.getFeatureClass();   
  17.     spatialFilter.setGeometryByRef(aoPgon);   
  18.     spatialFilter.setSpatialRel(esriSpatialRelEnum.esriSpatialRelWithin);   
  19.     spatialFilter.setGeometryField(featureClass.getShapeFieldName());   
  20.     IFeatureCursor featureCursor = featureClass.search(spatialFilter,  true );   
  21.     IFeature feature = featureCursor.nextFeature();   
  22.     ...   
  23.     }   
      SpatialFilter spatialFilter= (SpatialFilter)serverContext.createObject(SpatialFilter.getClsid());
  
  WebPolygon wPgon=(WebPolygon)event.getWebGeometry().toMapGeometry(event.getWebContext().getWebMap());
  GraphicElement ge = new GraphicElement();
  ge.setGeometry(wPgon);
   ge.setSymbol(this.getWebContext().getWebQuery().getPolygonGraphicSymbol());
   this.getWebContext().getWebGraphics().addGraphics(ge);
  
   Geometry geom = AGSUtil.toAGSGeometry(wPgon);
   com.esri.arcgisws.PolygonN pgonN = (com.esri.arcgisws.PolygonN)geom;
   Polygon aoPgon = (Polygon)AGSUtil.createArcObjectFromStub(pgonN, serverContext);
   
   for(int layerIndex=0;layerIndex<pMap.getLayerCount();layerIndex++){
    ILayer layer=pMap.getLayer(layerIndex);
    FeatureLayer featureLayer=(FeatureLayer)layer;
    IFeatureClass featureClass=featureLayer.getFeatureClass();
    spatialFilter.setGeometryByRef(aoPgon);
    spatialFilter.setSpatialRel(esriSpatialRelEnum.esriSpatialRelWithin);
    spatialFilter.setGeometryField(featureClass.getShapeFieldName());
    IFeatureCursor featureCursor = featureClass.search(spatialFilter, true);
    IFeature feature = featureCursor.nextFeature();
    ...
    }

在一般的情况下，建议使用第一种方式空间查询
