<aop:before method="before" pointcut-ref="myPointcut"/>

Method "before()" does not exist on the bean (referenced by containing <aop:aspect> element.
Invoking the provided "Create Method..." QuickFix generates a method wit the following signature:

public void before(JoinPoint pjp) throws Throwable {
}

"pjp" is more common for type "ProceedingJoinPoint" - used by "around" advice.
In this case simply "jp" would me more consistent.
