web.xml配置：

Java code

<resource-ref>        <description>MySQL Datasource v3hd</description>        <res-ref-name>jdbc/etweb</res-ref-name>        <res-type>javax.sql.DataSource</res-type>        <res-auth>Container</res-auth>    </resource-ref>

tomcat的server.xml配置：

Java code

<Context path="" docBase="ETweb" debug="5" reloadable="true" crossContext="true">                    <Resource name="jdbc/etweb" auth="Container" type="javax.sql.DataSource" maxAtive="70" maxIdle="30" maxWait="10000" username="root" password="root" driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://192.168.7.7:3306/payease_et?useUnicode=true&characterEncoding=GBK&autoReconnect=true"/>                </Context>

百度查了，说配置不一样会导致这个问题，但是我的配置是一致的；还有一种说法是在web-inf下把naming-common.jar,naming-factory.jar,naming-resources.jar三个jar包删除；但是我的工程里没有这几个包的。。

[解决办法]
我也出现了同样的错误
