public interface CommissionHome extends EJBHome {

RemoteException,CreateException;
public Commission findByPrimaryKey(CommissionBeanPK primaryKey)
throws RemoteException,FinderException;
public Enumeration findByNumber(String aNumber) throws
RemoteException,FinderException;
}
----------------- the remote interface
public interface Commission extends EJBObject {
public String getId() throws RemoteException;
public String getNumber() throws RemoteException;
public HCommission getHCommission() throws RemoteException;
public void setHCommission(HCommission hCommission) throws
RemoteException;
}
----------------- parts of the bean class
public class CommissionBean implements EntityBean {
public String id = null;
public String number = null;
private transient EntityContext context = null;
public String ejbCreate(String anId) throws CreateException {

return null;
}
...
public String getId() {
return id;
}
public String getNumber() {
return number;
}
public HCommission getHCommission() {
return new HCommission(id, number);
}
public void setHCommission(HCommission hCommission) {
if(id.equals(hCommission.getId()))
number = hCommission.getNumber();
}
