在glassfish 3.1.2中部署时，commons digester无法加载我的类

我最近面临以下问题：

1） 我的应用程序是一个企业应用程序。它是基于Java1.5构建的。部署在glassfish 2.1中，运行良好

现在我们发现有必要从Java1.5迁移到Java1.6，也有必要从GLASSFISH 2.1迁移到GLASSFISH 3.1.2

现在，在尝试这种迁移时，会出现问题。 在应用程序启动期间，使用commons digester解析XML配置文件并将其保存到对象。对于GlassFish2.1，在Java1.5和Java1.6中，digester解析都可以正常进行

但在glassfish 3.1.2中执行相同操作时，我们在应用程序启动过程中遇到以下错误：

以下日志文件来自应用程序日志：

尽管该类存在于构建中，但我们仍面临该类未找到错误

请提出同样的建议….

Hi，这在修改commons消化池源文件后得到解决。。似乎是一个普通的消化器错误。。修改Digester.java如下：public Digester（）{System.out.println（“到达1>>”）；this.setUseContextClassLoader（true）；}public Digester（SAXParser解析器）{System.out.println（“到达2>>”）；this.setUseContextClassLoader（true）；this.parser=parser；}public Digester（XMLReader reader）{System.out.println（“Comes to 3>>”）；this.setUseContextClassLoader（true）；this.reader=reader；是否有针对commons digester的补丁进行上述更改？非常感谢您的帮助！
