The relation between AccountOwnerEJB and AccountOwner, using EJB 2.0, would look like this:
in AccountOwnerEJB you would have the methods:
public abstract Collection getAccounts();
public void addAccount(Account account) throws RemoteException
{
this.getAccouts().addAccount();
}
...
Notice that the 'public static final Class accounts_type = Account.class;' is gone.
For the cmp-fields you just have abstract get/set methods.
For methods manipulating your cmp-fields you implement methods that relies on the abstract get/set methods.
In the descriptor for AccountOwnerEJB you would have:
<entity>
...
<cmp-field><field-name>accounts</field-name></cmp-field>
...
</entity>
You would then specify your relation inside the <relationships> tag,
<relationships>
<ejb-relation-name>accountowner-account</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>accountowner-has-accounts</ejb-relationship-role-name>
<multiplicity>one</multiplicity>
<role-source><ejb-name>com.acme.atm.ejb.AccountOwner</ejb-name></role-source>
<cmr-field>
<cmr-field-name>accounts</cmr-field-name>
<cmr-field-type>java.util.Collection</cmr-field-type>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>account-belongsto-accountowner</ejb-relationship-role-name>
<multiplicity>many</multiplicity>
<role-source><ejb-name>com.acme.atm.ejb.Account</ejb-name></role-source>
</ejb-relationship-role>
</relationships>
