服务器启动时来自org.cloudfoundry.runtime.env.CloudEnvironment.getServiceInfo的NullPointerException

Question

我正在尝试部署一个Tomcat7.0Web应用程序作为一个独立的应用程序，它基于带有my-sql服务的博客http://blog.cloudfoundry.org/2012/06/18/deploying-tomcat-7-using-the-standalone-framework/。虽然该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。下面是我在服务器启动时得到的异常：

这是使用以下命令获取的localhost日志

 vmc files log-app app/logs/localhost.2013-03-22.log

任何关于这个问题的帮助和见解都是非常感谢的。

另外，我想补充的是，我在推送期间将服务绑定到应用程序。以下是vmc app log-app命令的结果：

C:\Users\kinjal.doshi\apache-tomcat-7.0.35>vmc应用程序日志-应用程序日志-应用程序:运行平台: java单机版使用情况:2.56M x 1个实例urls: log-app.cloudfinddry.com services: mysql-2

我已经能够解决这个问题了。只需将mysql连接器jar添加到tomcat7.0lib文件夹
