How to compile AOP? My aspect never get called

[leewill]

I got this wired problem: my aspect only works on JBoss when I use Eclipse IDE to compile and build. It never get called on JBoss if I use Ant build. What's behind the scene of Eclipse and how to compile/build/deploy AOP stuff?
Detail info:
in the applicationContext.xml:

<aop:aspectj-autoproxy/>   
    
<bean id="procedureInteceptor" class="controller.aspect.MyAopClass"/>

In MyAopClass

@Aspect
public class MyAopClass { 
	private Log logger = LogFactory.getLog(getClass());	

	@Pointcut("execution(java.lang.String controller.lims.WorkStepController.*(..)) && args(request, ..)")
	private void workflowOperation(WebRequest request) {}
	
	/**
	 * Used to set returning view of each lims work flow step.
	 */	
	@Before("workflowOperation(request)")
	public void directingPage(WebRequest request) {
         ........
        }

In the controller this aspect adviced:

@Controller
@RequestMapping("/workflowStep.html")
public class WorkStepController {
	protected Log logger = LogFactory.getLog(getClass());
	
	@RequestMapping(method=RequestMethod.POST, params="processBtn")
	public String processStep(WebRequest request, @RequestParam("wfdId") String[] wfdIds) {
		.....
	}

The way my Ant build works is simple:
include aspectJrt and aspectJweaver.jar file classpath, compiled and WARed it, deploy to jboss.
