No, I do not pass PersonPK as an argument. I got PersonPK with
getPrimaryKey() from the EntityContext in PeronBean. What is fBPK ?

Some of the discussion I had directly with Rickard cause of the slow
mail transfer with this list (more then one our).

Sure, following.

I think that this scenario could happen often in the case of reusing
components.

Dito.
Here ejbActivate and ejbRemove from EhegatteBean (C):
---- snip ----
public void ejbRemove() throws RemoteException, RemoveException {
super.ejbRemove(); // Just for testing
person.remove();
person = null;
}
public void ejbActivate() throws RemoteException {
super.ejbActivate();
PersonHome personHome;
PersonPK key = new PersonPK();
try {
System.out.println("Versuche Person <" +
((EhegattePK)ectx.getPrimaryKey()).Mandant +
"> <" + ((EhegattePK)ectx.getPrimaryKey()).Nummer + "> <E> zu finden.");
key.Mandant = ((EhegattePK)ectx.getPrimaryKey()).Mandant;
key.Nummer = ((EhegattePK)ectx.getPrimaryKey()).Nummer;
key.Type = "E";
personHome = getPersonHome();
person = personHome.findByPrimaryKey(key);
} catch(NamingException nex) {
System.out.println("Naming: " + nex);
throw new RemoteException("Naming: " + nex.getMessage());
} catch(FinderException fex) {
System.out.println("Finder: " + fex);
throw new RemoteException("Finder: " + fex.getMessage());
} catch(Exception ex) {
System.out.println("Other: " + ex);
throw new RemoteException("Other: " + ex.getMessage());
}
}
---- snap ----
I wish Marry Cristmas and happy new year, too.
so long
