Tomcat5.5连接池的配置

Tomcat 5.5和tomcat5.0的配置是不一样的,Tomcat5.5的配置如下:

在server.xml文件中配置如下:

<Context path="/Recommend" reloadable="true" docBase="C:/eclipse/workspace/Recommend" workDir="C:/eclipse/workspace/Recommend/work">

<Resource name="jdbc/myoracle" auth="Container" type="javax.sql.DataSource"

maxActive="100" maxIdle="30" maxWait="10000"

username="spstest" password="sps0922"

driverClassName="oracle.jdbc.driver.OracleDriver"

url="jdbc:oracle:thin:@192.168.6.15:1521:ora9"/>

</Context>

在C:/Tomcat 5.5/common/lib目录下拷入class12.jar

class12.jar是oracle的jdbc的驱动程序不包

在web.xml中修改代码

<description>oralceDB</description>

<resource-ref>

<description>DB Connection</description>

<res-ref-name>jdbc/myoracle</res-ref-name>

<res-type>javax.sql.DataSource</res-type>

<res-auth>Container</res-auth>

</resource-ref>

测试代码

<%@ page import="javax.naming.Context" %>

<%@ page import="javax.sql.DataSource"%>

<%@ page import="javax.naming.InitialContext"%>

<%@ page import="java.sql.*"%>

<%

DataSource ds = null;

Context jndiCntx = new InitialContext();

ds =(DataSource)jndiCntx.lookup( "java:comp/env/jdbc/myoracle");

if(ds!=null){

System.out.println("Connection is OK!");

}

else

{

System.out.println("Connection is fail!");

}

Connection cn=ds.getConnection();

if(cn!=null){

System.out.println("cn is Ok!");

}

else

{

System.out.println("cn is fail!");

}

// Statement stmt = cn.createStatement();

// ResultSet rst = stmt.executeQuery("select * from BOOK");

// out.println("<p>rst is Ok!" + rst.next());

// while(rst.next()){

// System.out.println("<P>BOOK_CODE:" + rst.getString(1));

// }

cn.close();
