Tomcat連接池

之前接觸的都是dbcp和c3p0，tomcat7也提供了新的連接池，據說更好用，首先要修改context.xml文件：

<WatchedResource>WEB-INF/web.xml</WatchedResource>

    <!-- Uncomment this to disable session persistence across Tomcat restarts -->
    <!--
    <Manager pathname="" />
    -->

    <!-- Uncomment this to enable Comet connection tacking (provides events
         on session expiration as well as webapp lifecycle) -->
    <!--
    <Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />
    -->
	
	<Resource auth="Container" driverClassName="oracle.jdbc.driver.OracleDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" initialSize="5" maxActive="30" maxIdle="10" name="jdbc/******" password="******" type="javax.sql.DataSource" url="jdbc:oracle:thin:@***.***.***.***:****:***" username="******"/>			  

然後需要在tomcat的lib目錄中加入具體的數據庫驅動。
