I would have to strongishly disagree (although I know this is a religious issue). I think logic *should* be in the entity beans. Most definitions of object-oriented design goes something like 

"Each class encapsulates some data and all operations upon that data".

Personally I try to avoid using entity beans as dumb DTO:s. It seems so pre-EJB3:ish. "Why do we need a DTO?" "Hmm. Because we always have had them. Now be quiet and code" :-)

Yes. If an entity needs data, I pass in a repository so that it can use it itself (or even have the method lookup the repository itself) instead of having someone else do it and pass in the data.
