spring 数据源总是找不到

这是我的 xml 配置

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

<beans

	xmlns="http://www.springframework.org/schema/beans"

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

	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">







	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"     destroy-method="close">

		<property name="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver"/>

		<property name="url" value="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=bbs"/>

		<property name="username" value="sa"/>

		<property name="password" value="sa"/>

	</bean>

	

	  <bean id="userimip" class="mypack.db.UserImip">

        <property name="dataSource">

			<ref local="dataSource"/>

		</property>

	 </bean>

	

	

</beans>

这是我测试主方法

	public static void main(String args[])

	{

		UserBean userbean=new UserBean();

		userbean.setAge(4);

		ApplicationContext context = new  FileSystemXmlApplicationContext("../asdf/WebRoot/WEB-INF/applicationContext-hi.xml");//到 这步时候出现异常

		IUserDao user=(IUserDao)context.getBean("userimip");

		user.insertUSer(userbean);

	}

报的异常是
