求助啊：JSP连mysql，改成连oracle怎么改（c3p0）~~在线等！！

有一套JSP连Mysql的网站。想改成连oracle。看连接方法是用的c3p0。。在WEB-INF下面的classes底下有个文件叫c3p0-config.xml
里面：<?xml version="1.0" encoding="UTF-8"?><c3p0-config>
<named-config name="userApp">
<property name="driverClass">com.mysql.jdbc.Driver</property>
<property name="jdbcUrl">jdbc:mysql://localhost:3306/exam?useUnicode=true&amp;characterEncoding=utf-8</property>
<property name="user">root</property>
<property name="password">root</property>
<property name="acquireIncrement">2</property>
<property name="initialPoolSize">5</property>
<property name="minPoolSize">5</property>
<property name="maxPoolSize">20</property>
<property name="maxStatements">100</property>
<property name="maxStatementsPerConnection">5</property>

<property name="testConnectionOnCheckin">true</property>
<property name="automaticTestTable">tm_test</property>
<property name="idleConnectionTestPeriod">18000</property>
<property name="maxIdleTime">25000</property>
<property name="testConnectionOnCheckout">true</property>

<user-overrides user="master-of-the-universe"></user-overrides>
</named-config>
</c3p0-config> 
上网搜了把它改成了<?xml version="1.0" encoding="UTF-8"?><c3p0-config>
<named-config name="userApp">
<property name="driverClass">oracle.jdbc.driver.OracleDriver</property>
<property name="jdbcUrl">jdbc:oracle:thin:@localhost:1521:name</property>
<property name="user">scott</property>
<property name="password">tiger</property>
<property name="acquireIncrement">2</property>
<property name="initialPoolSize">5</property>
<property name="minPoolSize">5</property>
<property name="maxPoolSize">20</property>
<property name="maxStatements">100</property>
<property name="maxStatementsPerConnection">5</property>

<property name="testConnectionOnCheckin">true</property>
<property name="automaticTestTable">tm_test</property>
<property name="idleConnectionTestPeriod">18000</property>
<property name="maxIdleTime">25000</property>
<property name="testConnectionOnCheckout">true</property>

<user-overrides user="master-of-the-universe"></user-overrides>
</named-config>
</c3p0-config>
