I’m following the spring aspect programming tutorials at Javabrains. I’m in this tutorial specifically: http://javabrains.koushik.org/2011/08/spring-tutorial-27-writing-our-first.html I have the required libraries imported into the project and I get no warnings from the IDE, but when I run the code I get the following Exception:
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'triangle' defined in class path resource [spring.xml]: BeanPostProcessor before instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/aspectj/weaver/tools/PointcutDesignatorHandler

I have read through the comments on the tutorial page, and I have tried with different jars, but non of them seem to work. I always end up with the same exception.
You must add
aspectjweaver.jarto your CLASSPATH. How to do it precisely depends on your IDE.
