Re: [aspectj-users] can't weave using aspect in aspectpath

[Peter Backx <peter.backx@xxxxxxxxx>]

Matthew,

Yes, you are correct. The ANT script you wrote works perfect and
aspects are woven (this is actually what I'm using right now). It is
only when I move the aspect classes into a jar and onto the aspectpath
that it doesn't work. There's several ways I have checked this: first,
no closure classes are being generated and secondly, running the
programming does proove no aspects are executed.

If the "-showWeaveInfo" is in CVS and could help me diagnose the
problem, I might check this out later today, but I'm limited on time
right now.

regards,
Peter
