我已经在tomcat7中部署了一个网络应用程序，所有我要做的就是启动应用程序，但每次我尝试启动网络应用程序时，我总是遇到这个错误：
失败 - 无法启动上下文路径/ agileexpress中的应用程序
这就是我在我的日志上看到的，好像我的sql有问题

SEVERE: The web application [/agileexpress] registered the JDBC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

SEVERE: The web application [/agileexpress] appears to have started a thread named [MySQL Statement Cancellation Timer] but has failed to stop it. This is very likely to create a memory leak.
答案 0 :(得分：0)
将JDBC驱动程序移动到Tomcat（公共类加载器）lib /目录（在catalina.properties文件中定义，该文件通常位于CATALINA_HOME/lib）。这将告诉普通的类加载器加载驱动程序，你的webapp类加载器应该没有问题。
