GIS----你好！
我也做了例子在加载地图时还是在这里报错，
但是我用其他的加载方法就没有错误，如我用手动打开文档的方法来加载图时是正确的。
但一用到这个就出错，为什么？？？
但是只能用这个啊？因为我的程序启动时需要用它自动来加载地图

mapControl.addShapeFile(filePath, "country.shp");
报错信息：
Exception in initMap : AutomationException: 0x8000ffff - AutomationException: 0x8000ffff - at com.esri.arcgis.beans.map.MapControl.addShapeFile(Unknown Source)
我是用java+AE 来做的，请帮帮忙，这个问题困绕我好几天了，没有办法处理，我刚做这方面的开发没有什么经验，
请你多帮帮忙。
谢谢<img src="images/post/smile/dvbbs/em02.gif" /><img src="images/post/smile/dvbbs/em02.gif" />

你可以再看看这个例子:http://edn.esri.com/index.cfm?fa=codeExch.sampleDetail;pg=/arcobjects/9.1/Samples/Controls/MapControl/GeoEvents/Java/javaGeoEvent.htm 
另外注意下面的几句代码,代码是从上面的例子拿出来的 
 private String shapefilePath = ".." + File.separator + ".." + File.separator + "data
 MapBean localMapBean = this.mapBean; localMapBean.addShapeFile(this.shapefilePath, "world30"); localMapBean.addShapeFile(this.shapefilePath, "dissolvecntry");

这是整个程序,请大家帮忙调试一下,看看问题到底在哪里???
在我的调试中还是出错:
C:\arcgis\ArcTutor\LinearReferencing\ ..\..\..\..\..\data /E:/eclipse3.2work/testGis/bin/ 图层加载出错AutomationException: Exception in initMap : AutomationException: 0x80070057 - AutomationException: 0x80070057 - at com.esri.arcgis.beans.map.MapControl.getLayer(Unknown Source)
