[aspectj-users] java.lang.ArrayIndexOutOfBoundsException Error

["Lau Man Kwong" <kinthecastle@xxxxxxxxx>]

Hi,

 

I'm new to aspectj. When I do some practice on aspectj, an error "java.lang.ArrayIndexOutOfBoundsException: 0 at com.at.aspect.LoggingAspect.log(Unknown Source)" was encountered. I have searched on internet but get no answer. Can you give me some hints for this error?

 

I am using AspectJ 1.5.4, Spring 2.0 and JDK 5.0 on this project.

 

I have attached some codes and stacktrace. Thanks!!!

 

Regards,

Terry

 

LoggingAspect.java

package com.at.aspect;

import org.aspectj.lang.ProceedingJoinPoint;

public class LoggingAspect {
 public Object log(ProceedingJoinPoint call) throws Throwable
    {
        System.out.println("from logging aspect: entering method [" + call.toShortString()
                            +"] with param:"+call.getArgs()[0] );

        Object point =  call.proceed();

        System.out.println("from logging aspect: exiting method [" + call.toShortString()  
                            + "with return as:" +point);       

        return point;
    }

}
