mysql-oracle数据库连接的xml文件怎么改成Mysql能用的？

原数据库是oracle的，现在在Mysql上建了个一样的，怎么改文件才能连接上数据库？

**现在尝试过：
1.只改url，driverClassName，username,password，之后tomcat就出问题了

2.我把下面这个xml删掉了，用建立数据库连接类的方法，错误是这样的
Struts Problem Report

Struts has detected an unhandled exception:

Messages: 1.Io ??: The Network Adapter could not establish the connection
2.Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: Io ??: The Network Adapter could not establish the connection

File: oracle/jdbc/driver/DatabaseError.java
Line number: 112 **

原来的applicationContext.xml是这样的：
