You'd need to create a PrimaryKeyBean like mentioned in earlier posts today
only with fields that store the last number issued for each of your other
beans that need these ids. Then create one instance of that PrimaryKeyBean
to do the work. Then in the ejbCreate() method, call some findBy on
PrimaryKeyHome to get the PrimaryKey remote interface for that instance, and
call a method on the remote interface that returns the next id for the bean
that is to be created. Like:
public Long ejbCreate() throws RemoteException, CreateException{
PrimaryKey pk=null;
PrimaryKeyHome
pkhome=(PrimaryKeyHome)getHome("primaryKey/PrimaryKey",PrimaryKeyHome.class)
;
try{
pk=pkhome.findByPrimaryKey(new Integer(0));
}
catch(Exception e){
pk=pkhome.create();
}
cancelled=false;
reservationID=pk.getReservationID();
return null;
}

Subject: [JBoss-user] Auto-increment CMP primary key?
Another newbie question:
Using a totally out-of-the-box JBoss+TomCat, I built a container managed
EJB. The EJB's primary key is a Long; the idea is that a simple serial
number is sufficient. In my bean's ejbCreate(), is there a recommended
way to automatically generate the next Long?
Thanks,
