我正在尝试基于博客http://blog.cloudfoundry.org/2012/06/18/deploying-tomcat-7-using-the-standalone-framework/ 将tomcat 7.0 Web 应用程序部署为独立应用程序-sql 服务。虽然此应用程序在没有服务的情况下运行良好，但当我将 MySQL 服务绑定到该应用程序时，服务器无法启动。以下是我在服务器启动时遇到的异常：

这是使用获取的 localhost 日志
vmc files log-app app/logs/localhost.2013-03-22.log
非常感谢有关此问题的任何帮助和见解。
另外，我想补充一点，我在推送期间将服务绑定到应用程序。这是 vmc app log-app 命令的结果：
