3rd Rule Example Code

The method declaration does not match the EJB-QL example.
Either change:

WHERE m.genre = ?2 AND m.director.degrees < ?1
... to:
WHERE m.genre = ?2 AND m.director.directorId < ?1

Or change:

public String ejbHomeListMoviesByDirectorAndGenre(String dirID, String genre)
... to:
public String ejbHomeListMoviesByDirectorAndGenre(String degrees, String genre)

Basically, argument 1 in the EJB-QL implies Director.degrees, whereas argument 1 in
the method implies Director.directorId

Current Content: A side note which reads:
"Now we actually do the writing. Remember, the writer is chained to the *input stream* from the Socket ....".
Correct: I think it should be *output stream* from the Socket instead of input stream.
