ubuntumysqltomcat阿里云

1、程序没问题，在本机上调试无误，struts2 spting hibernate
2、在阿里云服务器上配置了 JDK 1.7 + tomcat7 + mysql5.1 ， OS:ubuntu64
3、将应用部署后，JSP 页面访问正常，只要涉及到连接数据库就会有如下提示

org.hibernate.exception.GenericJDBCException: Cannot open connection
org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:126)
org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:114)
org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66)
org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:52)
org.hibernate.jdbc.ConnectionManager.openConnection(ConnectionManager.java:449)
org.hibernate.jdbc.ConnectionManager.getConnection(ConnectionManager.java:167)
org.hibernate.jdbc.JDBCContext.connection(JDBCContext.java:142)
org.hibernate.transaction.JDBCTransaction.begin(JDBCTransaction.java:85)
org.hibernate.impl.SessionImpl.beginTransaction(SessionImpl.java:1354)
com.bfy.action.LoginAction.execute(LoginAction.java:89)
sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

。。。。。。。。。。。。

4、怀疑XML文件读取也有问题，去掉过滤器直接访问一些ACTION，提示没有对应的result
5、应用池内文件权限均为 777
6、mysql数据库工作正常，应用所使用的为root用户，不是权限问题
