[Build 20050111]
Let's have this database structure:
CREATE TABLE TAB1
(KEY1 INTEGER  NOT NULL,
PRIMARY KEY (KEY1)
);
CREATE TABLE TAB2
(KEY1 INTEGER  NOT NULL,
 VALUE2 CHARACTER (10),
PRIMARY KEY (KEY1),
FOREIGN KEY (KEY1)  REFERENCES TAB1(KEY1)
);
This is simple 1:1 relationship. I generated CMP
beans, the correct elements in DD was generated:

<ejb-relationship-role>      
<ejb-relationship-role-name>Key1</ejb-relationship-role-name>
        <multiplicity>One</multiplicity>
        <relationship-role-source>
          <ejb-name>Tab1</ejb-name>
......
Then I go to the visual sun-ejb-jar.xml DD and
open Cmp Mapping tab, there is <multilple> type
for this relationship.
I guess, that type isn't multiple, there should be
type like Single or .....
