Tomcat报错问题
我的strusts-config.xml 里面的配置是这样的

XML code

<data-sources>
        <data-source key="bbsDB" type="org.apache.commons.dbcp.BasicDataSource">
            <set-property property="driverClassName" value="org.gjt.mm.mysql.Driver" />
            <set-property property="url" value="jdbc:mysql://localhost:3306/bbs?useUnicode=true&amp;characterEncoding=UTF-8" />
            <set-property property="username" value="root" />
            <set-property property="password" value="liang" />
        </data-source>
    </data-sources>

Tomcat启动时报了三个错误
