omcat
6的配置和以前的不同，不推荐在server.xml中进行配置，而是在context.xml中进行配置才是更好的方法。是站点目录下的
context.xml文件，不是tomcat_home/conf下的。tomcat_home/webapps/yourApp/META-INF
/context.xml，没有的话就创建一个，这样可以在不同的网站下单独配置连接池了，并且不需要重启Tomcat，Tomcat会自动重载。
context.xml：
<?
xml
version
="1.0"
encoding
="UTF-8"
?>
<
Context
reloadable
="true"
crossContext
="true"
>
<!-- Default set of monitored resources
-->
<
WatchedResource
>
WEB-INF/web.xml</
WatchedResource
>
<!-- Uncomment this to disable session persistence across Tomcat restarts
-->
<!--
<Manager pathname="" />
-->
<
Resource
name
="ds/test"
//其中ds/test是数据源名称，通过JNDI调用
auth
="spark"
type
="javax.sql.DataSource"
driverClassName
="oracle.jdbc.driver.OracleDriver"
url
="jdbc:oracle:thin:@localhost:1521:orcl"
username
="scott"
password
="test"
maxActive
="20"
maxIdle
="10"
maxWait
="-1"
/>
</
Context

最后配置成功后在java代码中获得Connection对象
Context context = new
InitialContext();
//获得数据源
DataSource ds = context.lookup("java:comp/env/ds/test"
);
//获取连接
Connection conn = ds.getConnection();
InitialContext();
//获得数据源
DataSource ds = context.lookup("java:comp/env/ds/test"
);
//获取连接
Connection conn = ds.getConnection();
