tomcat6.0配置数据源

J2ee 初步

Tomcat 数据源配置

1. 找到 C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf 下面的 context 文件修改 配置如下

< Context >

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

< Resource name = "jdbc/dggj"    

        auth = "Container"        

        type = "javax.sql.DataSource"        

        driverClassName = "com.mysql.jdbc.Driver"        

        url = "jdbc:mysql://localhost:3306/dggj"        

        username = "root"        

        password = "123456"        

        maxActive = "100"        

        maxIdle = "30"        

      maxWait = "10000" />

</ Context >

 

2. 修改 Web 应用的 web.xml 如下

<? xml version = "1.0" encoding = "UTF-8" ?>

< web-app version = "2.4"

    xmlns = "http://java.sun.com/xml/ns/j2ee"

    xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation = "http://java.sun.com/xml/ns/j2ee

    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >

    < resource-ref >         

         < description > DB Connection </ description >         

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

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

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

       </ resource-ref >     

</ web-app >

 

3. 写测试程序 vtest.jsp 如下

<%@ page language = "java" import = "java.util.*,javax.naming.*,javax.sql.*" pageEncoding = "ISO-8859-1" %>

< jsp:directive.page import = "java.sql.Connection" />

< jsp:directive.page import = "java.sql.Statement" />

<%

Context ctx= new InitialContext();

DataSource ds=(DataSource)ctx.lookup( "java:comp/env/jdbc/dggj" );

 

Connection con=ds.getConnection();

Statement st=con.createStatement();

  java.sql.ResultSet rs=st.executeQuery( "select * from tbl_station" );

  while (rs.next())

  {

     System.out.println(rs.getObject(2));

  }

%>

<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" >

< html >

  < head >

    < title > My JSP 'judi.jsp' starting page </ title >

  </ head >

  < body >

    This is my JSP page. < br >

  </ body >

</ html >

Tomcat6.0 的配置跟 v5.x 的配置稍微有差别

 

。。。配这么复杂的数据源，就是为了用jsp去写业务啊。。倒不如直接jsp里面搞定数据源得了
