Aspect Oriented Programming profiling execution time

I am trying to profile execution time of a simple method, using Aop. when i try to execute the code i keep getting the error repeatedly.

import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class SpringAOPDemo { public static void main(String[] args) { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext( "applicationContext.xml"); Business bc = (Business) context.getBean("myBusinessClass"); bc.doSomeOperation(); } } 

This is my XML class, ApplicationContext.XML

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"> <!-- Enable the @AspectJ support --> <aop:aspectj-autoproxy /> <bean id="businessProfiler" class="com.veerasundar.spring.aop.BusinessProfiler" /> <bean id="myBusinessClass" class="com.veerasundar.spring.aop.BusinessImpl" /> </beans> 

I keep on getting this error,
