Re: [aspectj-users] Using an introduced method from one apsect in anothe

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi,

That should work fine.  You either have to compile everything together
(using ajc) or two stage compile, first the aspects that introduce the
method you want to access from the other aspect (e.g. foo) then the
aspects that use it.

Let me know if you have trouble with it.

cheers,
Andy
