Re: [aspectj-users] Running aspectj on application server

[danny.foncke@xxxxxxxxxxxx]

The context changes - where you are at the moment of advice

'execution' and you are in the called class, the class containing the
method
'call' and you are in the calling class

So, as Doug pointed out,  be aware when you define you're 'call' pointcuts
that the weaver sees the calling class when the weaving is done
