javax.faces.el.EvaluationException: java.sql.SQLException: Io 异常:

100分：Spring JDBC Io 异常: Connection reset
请各位大侠帮忙看看~~
我在beans-config.xml中这样配置dataSource:

XML code

<bean id="dataSource"      class="org.springframework.jdbc.datasource.DriverManagerDataSource">      <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>      <property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:TDMS"/>      <property name="username" value="system"/>      <property name="password" value="huangdezhi"/>  </bean>

然后在java文件中使用Spring的JdbcTemplate对象：

Java code

jdbcTemplate.update("INSERT INTO DATABASES (DBNAME, DBPASSWORD, DBCREATOR, DBDESCRIPTION)"                + "VALUES('" + name + "','" + password + "','" + creator + "','" + description + "')");

然后运行时，tomcat抛出了这样的异常：
严重: java.sql.SQLException: Io 异常: Connection reset
javax.faces.el.EvaluationException: java.sql.SQLException: Io 异常: Connection reset

我是在哪儿写错了吗？那个异常看得我一头雾水。。。请各位帮帮忙啦。


------解决方案--------------------
严重: java.sql.SQLException: Io 异常: Connection reset 

是你的连接写错了，也许是url,也许是用户名和密码。

如果服务器不在你本机，你远程连数据库，那么我更怀疑是防火墙问题。
------解决方案--------------------
端口连接失败就是LISTENER服务没有打开，在服务里找到ORACLE的LISTENER启动就行了。
