[jboss-user] [JBoss AOP] - Pls help with a simple Mixin problem

[guava]

Hi,

I'm started to use the Introduction feature of JBossAOP and can not seem to get the Mixin working. Any help will be appreciated. I have one Pojo, one Aspect, one Mixin, and an interface the mixin implements. I'm running these in the same directory as the examples provided by JbossAOP. Following are the classes:

//------ MyPojo
public class MyPojo {
}

//------ MyInf
public interface MyInf {
	String hello(String h);
}

//-----MyMixin
public class MyMixin implements MyInf {
    public String hello(String h) {
        return "Hello " + h;
    }
}

//---- MyAspect
import org.jboss.aop.Aspect;
import org.jboss.aop.Mixin;
import org.jboss.aop.Introduction;

@Aspect
public class MyAspect
{
   @Mixin (target=MyPojo.class, interfaces={MyInf.class})
   public static MyMixin createMyMixin() {
       return new MyMixin();
   }
}

I'm getting a javassist.NotFoundException: LMyMixin when I run aop compiler. 

Following are the build file and the stack trace:
