Hey all.
assume we have two CMP beans TeamBean, PlayerBean
the relationship is one to many and bidirectional.
TeamBean has the following CMP fields:
name, city
TeamBean has setter and getter methods for these fields.
the database schema for TeamBean is :
NAME, CITY
PlayerBean has the following CMP fields :
id, email
PlayerBean has setter and getter methods for these fields.
the database schema for PlayerBean is :
ID, EMAIL, TEAM (TEAM is FK)
I have the following code (in a facade bean):
public void addPlayer(id, name, String team) {
LocalPlayer lp = playerHome.create(id, name);
LocalTeam lt = teamHome.findByPrimayKey(team);
lp.setTeamLocal(lt);
}
the container will insert "a right" value at TEAM column of Player table.
but I have read some articles that said :
we should a CMP field called team in PlayerBean and create setter and getter methods for this CMP field.
this is because (as the article says), we want to create a transfer object for PlayerBean with these fields :
id, email, team
so we able to write :
new PlayerDO(local.getID( ), local.getEmail( ), local.getTeam( ));
in my case (which I didn't create getTeam( )), I can write :
new PlayerDO(local.getID( ), local.getEmail( ), local.getTeamLocal( ).getName( ));
what is the right approach ??
as far as I know, if we create a method like setTeam( ), this may damage the mapping
that has been done by the container.
should I create a CMP field called team and create setter and getter methods for it ?
