I think I figured out a solution....I added comment.setCompetition( arch )
to the code below in my action class. Not sure if this is the best solution
but it works and I'm happy.
Comment comment = new Comment();
comment.setDate(valueDate);
comment.setCopy(valueCopy);
comment.setUser(valueUser);
comment.setCompetition( arch );
arch.getComments().add(comment);
mgr.saveArch(arch);

The comments are sorted in descending order.... In LookupManagerImpl I'm
returning a list of wrapper objects that mirror the comment objects. I did
this so that I could store the id's numbers of the parent objects....and
make them accessible from my jsp pages. below are the lookup functions.
