| public static java.lang.String | listArtistNames(java.util.Set artists)Build a parenthetical, comma-separated list of artist names.
StringBuffer result = new StringBuffer();

}
if (result.length() > 0) {

}
return result.toString();

| public static void | main(java.lang.String[] args)Look up and print some tracks when invoked from the command line.
// Create a configuration based on the properties file we've put
// in the standard place.
Configuration config = new Configuration();
// Tell it about the classes we want mapped, taking advantage of
// the way we've named their mapping documents.
config.addClass(Track.class).addClass(Artist.class);
// Get the session factory we can use for persistence
SessionFactory sessionFactory = config.buildSessionFactory();
// Ask for a session using the JDBC information we've configured
Session session = sessionFactory.openSession();
try {
// Print the tracks that will fit in seven minutes
List tracks = tracksNoLongerThan(Time.valueOf("00:07:00"),

for (Iterator comIter = aTrack.getComments().iterator() ;

}
} finally {
// No matter what, close the session
session.close();
}
// Clean up after ourselves
sessionFactory.close();

| public static java.util.List | tracksNoLongerThan(java.sql.Time length, Session session)Retrieve any tracks that fit in the specified amount of time.
Query query = session.getNamedQuery(
"com.oreilly.hh.tracksNoLongerThan");
query.setTime("length", length);
return query.list();
