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
