运行grails run app时生成web.xml文件时出错

我下载了grails 2.0.4并运行了以下命令：

  grails create-app contactmanager
  cd contactmanager
  grails clean
  grails run-app

最后一个命令将返回此错误堆栈跟踪：

您是否在任何时候操纵过jre/lib/ext目录？ 我这样做是为了在weblogic上设置saml环境。我复制了这些文件

• 序列化程序-2.10.0.jar
• xalan-2.7.1.jar
• xercesImpl-2.10.0.jar
• xml-API-2.10.0.jar
• xml-resolver-1.2.jar

这导致了xml解析中的问题。我从jre/lib/ext中删除了这些文件，它开始工作了。不知道您是否有同样的问题。

您使用的是哪种JDK？是Oracle还是IBM JDK？你能测试升级到1.7吗？如果使用IBM JDK，则需要特定的设置。
