ibatis连接oracle遇到的问题！ 急 大家帮助！！

   之前项目连接的mysql数据库 。现在把datasource的参数修改成 oracle的配置 <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close" dependency-check="none">
<property name="driverClass">
<value>oracle.jdbc.driver.OracleDriver</value>
</property>
<property name="jdbcUrl">
<value>jdbc:oracle:thin:@192.168.1.111:1521:stm</value>
</property>
<property name="user">
<value>system</value>
</property>
<property name="password">
<value>system</value>
</property>之前是mysql配置。在重新部署之后，项目可以起来 。但是老是报错 。而且是报mysql的错误 。我把mysql的服务关闭在试试 com.mchange.v2.c3p0.impl.NewPooledConnection@6646fc invalidated by Exception: com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception: ** BEGIN NESTED EXCEPTION ** java.net.SocketException

at com.mysql.jdbc.MysqlIO.reuseAndReadPacket(MysqlIO.java:2515)就报这样的错 。事实证明 我想的应该是正确的 ibatis 根本就没和oracle连上 。。但是什么原因就没搞懂了 大家帮助啊 。能找原因找原因 ，或是直接给我说怎样让ibatis配置oracle  ！ 谢谢
