Question

当我使用app引擎开发我的应用程序时，我只想使用以下代码读取存储在gaevfs中的文件：this.shpAccessFile = new RandomAccessFile（this.shpFileName，“r”）;但它抛出新的AccessControlException（“访问被拒绝”+烫发，烫发）;所以有人能告诉我如何解决这个问题吗？

java.security.AccessControlException: access denied (java.io.FilePermission gae:\F:\workspace\GeoCloud\war\gaevfs\cecc8aa0-7405-102e-b976-026d7f000001\longrive.shp read)
