Struts datasource 配置问题

刚开始我的配置文件是这样写的::

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<struts-config>
<data-sources>
<data-source key="DBsource" type="org.apache.commons.dbcp.BasicDataSource">
<set-property property="driverName" value="org.gjt.mm.mysql.Driver"></set-property>
<set-property property="url" value="jdbc:mysql://localhost:3306/mydb"></set-property>
<set-property property="username" value="mzy"></set-property>
<set-property property="password" value="root"></set-property>
</data-source>
</data-sources>
<form-beans>
<form-bean name="LogonForm" type="nn.fm.form.LogonForm"></form-bean>

启动tomcat5.时出错:::

找了半天不知道是什么原因,经过不断的摸索,哈哈,找到了答案:

原来是property="driverName" 这里的属性名是不变的啊,一定要是 driverClassName哦!!

以后要小心这样的小问题啦!
