Re: [aspectj-users] class location question

[Simone Gianni <simoneg@xxxxxxxxxx>]

Hi Neo,
this is not aspectj related but java related. If you move a class from a
package to another (like from the "sensor" package to the default
package), you must change your imports in other classes accordingly,
otherwise they will still search the classes in the old package instead
of the new one. Remove those imports if they are in a class in the same
package, or at least remove the "sensor" part from them, since the
sensor package does not exist anymore.

Hope this helps,
Simone
