我正在修改继承的代码，并不断得到一个奇怪的“无法找到符号”的错误，这是抛出我。什么导致此Java“无法找到符号”错误？

我有三重检查，但不能发现任何错误的代码迄今。我在Netbeans 7.0.1中构建它。我应该提到我在构建时遇到此错误，但是我可以在没有任何问题（但）的情况下运行该Web应用程序。但我担心这可能会回来咬在后面。
我只注意到，该CompanyDAO类以上的类似名称的文件带有格式文件树：CompanyDAO $ ChildType＃的.class（＃对应的数字）我猜它没有重新编译该类以生成额外的添加的类型I。我怎样才能做到这一点？
试图清理项目/执行完整的重建？ – solendil
你试过干净的版本吗？你在classpath中是否有一个jar或其他文件夹，可能还有一个CompanyDAO类的副本？ – gkamal
