import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;

@Aspect
public class AuditLogProcessor
{
    private static Logger log = Logger.getLogger(AuditLogProcessor.class);

    @After("execution(* aop.GreetingService.sayGreeting())")
    public void after() {
        log.info("==> after");
    }

    @After("execution(* aop.GreetingService.sayGreeting())")
    public void before() {

package aop;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.FileSystemResource;

public class HelloApp {
	public static void main(String args[]) {
		BeanFactory factory = 
			new XmlBeanFactory( 
					new FileSystemResource("aop/spring.xml") );
		
		GreetingService greetingServiceImpl = (GreetingService) factory.getBean("GreetingService");
		greetingServiceImpl.sayGreeting();

Change XmlBeanFactory to ClasspathXmlApplicationContext. I haven't checked the rest of the code, but XmlBeanFactory definitely won't work.

public static void main(String args[]) {
		ClassPathXmlApplicationContext factory = 
			new ClassPathXmlApplicationContext("aop/spring.xml");
		
		GreetingService greetingServiceImpl = (GreetingService) factory.getBean("GreetingService");
		greetingServiceImpl.sayGreeting();
