AspectJ LTW using Spring

[Joe San]

Guys,

I have an aspect called LoggingAspect as defined below:

package com.quintilis31.home.aspect;

import org.apache.log4j.Logger;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.*;

/**
 * Created by IntelliJ IDEA.
 * User: jothi
 * Date: Dec 8, 2010
 * Time: 9:06:09 PM
 * To change this template use File | Settings | File Templates.
 */
@Aspect
public final class LoggingAspect {

    /** The Logger implementation for this class. */
    private static final Logger LOG = Logger.getLogger(LoggingAspect.class);

    @Pointcut("within(com.quintilis31.home..*)")
    private void traceAllClasses() {}

    @Pointcut("execution(public * *(..))")
    private void traceAllPublicMethods() {}

    @Pointcut("traceAllClasses() && traceAllPublicMethods()")
    private void traceAllPublicMethodsInAllClasses() {}

    @Pointcut("within(com.quintilis31.home.core.content.service.impl.ContentServiceImpl) && " +
              "within(com.quintilis31.home.core.user.service.impl.UserServiceImpl)")
    private void traceAllServiceMethodsForReturnValue() {}

    @Before("traceAllPublicMethodsInAllClasses()")
    public void traceBefore(JoinPoint jp) {
        LOG.info("Tracing " + jp.getSignature().getName());
        System.out.println("Tracing " + jp.getSignature().getName());
    }

    @After("traceAllPublicMethodsInAllClasses()")
    public void traceAfter(JoinPoint jp) {
        LOG.info("Tracing " + jp.getSignature().getName());
    }

    @AfterReturning(pointcut="traceAllServiceMethodsForReturnValue()", returning="retVal")
    public void traceAfterReturning(Object retVal) {
        LOG.info("Printing Return Value " + retVal);
    }

}

My application logic is built using Spring. I have a simple JUnit test case to test my service. But I do not see the advice?? Any suggestions as to where the fault could be? Following is my aop.xml that I have in the META-INF folder of my application.

<aspectj>

    <weaver options="-verbose -showWeaveInfo">

        <!-- only weave classes in our application-specific packages -->
        <include within="com.quintilis31.home..*"/>

    </weaver>

    <aspects>

        <!-- weave in just this aspect -->        
        <aspect name="com.quintilis31.home.aspect.LoggingAspect"/>
                    
    </aspects>

  </aspectj>

[Joe San]

According to the Spring documentation, I do not need to do any explicit LTW when I use Spring AOP like I did above in my example. But why does it fail to work? When I run my test class I fail to see the advices. Any suggestions please!

[Joe San]

I have configured the Spring IDE on my Eclipse Helios. But why is that I could not view the aspects and advices that I have defined as above?

Tomcat start up now shows the following issue.

Which jar file do I have to put under Tomcat's lib directory?

[Joe San]

I added spring-tomcat-weaver.jar to the tomcat lib directory. But now it looks like my app itself is not deployed. Below is what I see in the log files. Also when I look at the Tomcat webapps directory, I just see my war file but the exploded war is not there.

And of course accessing the web application gives a 404.
