Hi Marco,

I think you might have the difference right - aspectpath contains
aspects to (potentially) apply to everything the weaver sees, and
inpath contains anything you want to be woven.

The setup you describe sounds right, for doing the weaving in the
marcoAspect project. You can try enabling the "output weaving messages
to problems view" option (under AspectJ Compiler > Other) if you
haven't already, to see if it's actually weaving anything. What is not
working exactly? Note that the woven classes go in the output folder
of the marcoAspect project, so they won't get automatically deployed
to the app server. The other possible arrangement would be to make
marcoWeb an AspectJ project, then use the aspectpath setting to get
the aspects from the other project.

Regards,

Matt.
