Re: [aspectj-users] declare parents with super/sub classes

["Jennifer Baldwin" <jebaldwin@xxxxxxxxx>]

No, I'm not using Java 5. I'm actually using what Java 1.3 since the
version of the system I'm using is 2 years old.

I previously had two aspects that I wove in a row, the first with the
supertype, the last with the subtype, which worked. But of course it's
not overly elegant to have however many of these compiled in a row (it
didn't work to include them in the same invocation of ajc) where the
aspect implements the same functionality so I was hoping there was a
better way but considering the use of the interface, I think that
there probably isn't :-)
