I have been working on enterprise Java projects (basic consulting) which uses eclipse almost exclusively. We do not use Smurf naming convention (SmurfDto, SmurfDao, SmurfService, SmurfController) just for being able to find related classes. We do it because eclipse seems to randomly refactor classes based on non fully qualified names. No to naming something Constants as that will (randomly) refactor the codebase to break partially if you decide later to refactor something in that class.

I have tried everything from no vendor plugins for app servers to a vanilla eclipse and it still messes up.

I do like the product, but it can be very frustrating at times.
