以下的文章主要讲述的是如何在tomcat5中正确配置MySQL数据源，以下的文章我们主要是对tomcat5中正确配置MySQL数据源的实际操作步骤的详细介绍，以下就是文章的具体操作步骤描述。一、配置MySQL环境变量： softe version:tomcat(一个很好用的JSP运行平台)5.0

以下的文章主要讲述的是如何在tomcat5中正确配置MySQL数据源，以下的文章我们主要是对tomcat5中正确配置MySQL数据源的实际操作步骤的详细介绍，以下就是文章的具体操作步骤描述。

一、配置MySQL环境变量：

softe version:tomcat(一个很好用的JSP运行平台)5.0.12/MySQL(和PHP搭配之最佳组合)4.1.7/MySQL(和PHP搭配之最佳组合)_driver---

MySQL(和PHP搭配之最佳组合)-connector-java-3.1.4-beta-bin.jar

MySQL(和PHP搭配之最佳组合)驱动程序可从www.MySQL(和PHP搭配之最佳组合).com官方网站下载

路径：

tomcat(一个很好用的JSP运行平台)5在d:mywebomcat5；

MySQL(和PHP搭配之最佳组合)在C:Program FilesMySQL(和PHP搭配之最佳组合)MySQL(和PHP搭配之最佳组合) Server 4.1

Path(在原来的基础上加上）：

<ol class="dp-xml">
<li class="alt"><span><span>d:mywebomcat5in;d:mywebjdk1.4;d:myweb  </span></span></li>
<li><span>jdk1.4in;  </span></li>
<li class="alt"><span>d:mywebomcat5commonlibservlet-api.jar;C:Program Files  </span></li>
<li>MySQL<span>(和PHP搭配之最佳组合)</span>MySQL<span>(和PHP搭配之最佳组合) Server4.1in  </span>
</li>
<li class="alt"><span>CLASSPATH:d:mywebomcat5commonlibservlet-api.jar;d:myweb  </span></li>
<li><span>tomcat(一个很好用的JSP运行平台)5commonlibjsp(SUN企业级应用的首选)-api.jar  </span></li>
<li class="alt"><span>JAVA_HOME:d:mywebjdk1.4  </span></li>
<li><span>CATALINA_HOME:d:mywebomcat5 </span></li>
</ol>

Copy after login

二、建立测试数据库

在MySQL(和PHP搭配之最佳组合)中建立一个forumdb数据库，同时创建一个表member如下：

<ol class="dp-xml">
<li class="alt"><span><span>create database forumdb;  </span></span></li>
<li><span>create table member  </span></li>
<li class="alt"><span>(  </span></li>
<li><span>id int,  </span></li>
<li class="alt"><span>name varchar(6)  </span></li>
<li><span>); </span></li>
</ol>

Copy after login

然后插入两条测试数据如下：

<ol class="dp-xml">
<li class="alt"><span><span>insert into member values(1,"zhang");  </span></span></li>
<li><span>insert into member values(2,"wang"); </span></li>
</ol>

Copy after login

至此，数据库准备完毕。

三、配置server.xml(标准化越来越近了)

注：我的web在d:mywebmyapps

首先要将MySQL(和PHP搭配之最佳组合)的驱动程序放到d:mywebomcat5commonlib下面，一定要放".jar"的文件，如是".zip"的文件直接改为.jar即可。

用文本编辑器打开D:omcat5confserver.xml(标准化越来越近了)，找到结束标志，然后在之前加上如下语句：

<ol class="dp-xml">
<li class="alt"><span><span class="tag"><span class="tag-name">Context</span><span> </span><span class="attribute">path</span><span>=</span><span class="attribute-value">"/myapps"</span><span> </span><span class="attribute">docBase</span><span>=</span><span class="attribute-value">"d:mywebmyapps"</span><span> </span><span class="attribute">debug</span><span>=</span><span class="attribute-value">"0"</span><span> </span></span></span></li>
<li>
