数据源配置文件：

<Context workDir="work\Catalina\localhost\suntek" path="/suntek" displayName="Struts Example Application" docBase="E:/suntek/suntek" reloadable="true">

    <parameter>
      <name>password</name>
      <value>sa</value>

    <parameter>

    </parameter>
    <parameter>
      <name>maxIdle</name>
      <value>2</value>
    </parameter>
  </ResourceParams>
</Context>
程序调用：
DataSource ds=(DataSource)ctx.lookup("java:comp/env/jdbc/suntekDB");//指定所使用的连接池
