Please advise on the following issues described below: 1. no ejb-relationship-role-name defined error. 2. serialized UserType being stored in RDBMS table users, instead of foreign key integer.
I have 2 entities: User and UserType. The relationship between the User entity and UserType etity is as follows: 1 User can only have 1 UserType, but 1 UserType can belong to many Users. Furthermore, User maintains a reference to UserType, but UserType does not have a reference to User. So in ejb-jar.xml, we have defined the one-to-many unidirectional relationship between the UserEJB and the UserTypeEJB is as follows: <ejb-relation> <ejb-relation-name>User-UserType</ejb-relation-name> <ejb-relationship-role> One <relationship-role-source> <ejb-name>UserTypeEJB</ejb-name> </relationship-role-source> </ejb-relationship-role> <ejb-relationship-role> <ejb-relationship-role-name>User-has-a-UserType</ejb-relationship-role-name> Many <relationship-role-source> <ejb-name>UserEJB</ejb-name> </relationship-role-source> <cmr-field> <cmr-field-name>userTypeLocal</cmr-field-name> </cmr-field> </ejb-relationship-role> <ejb-relationship-role-name>UserType-has-many-Users</ejb-relationship-role-name> </ejb-relation> I have also added the following to jbosscmp-jdbc.xml: <ejb-relation> <ejb-relation-name>User-UserType</ejb-relation-name> <foreign-key-mapping/> <ejb-relationship-role> <ejb-relationship-role-name>UserType-has-many-Users</ejb-relationship-role-name> </ejb-relationship-role> <ejb-relationship-role> <ejb-relationship-role-name>User-has-a-UserType</ejb-relationship-role-name> <fk-constraint>true</fk-constraint> <key-fields> <key-field> <field-name>userTypeLocal</field-name> <column-name>user_type_id</column-name> </key-field> </key-fields> </ejb-relationship-role> </ejb-relation> However, when the inserting the above xml fragment into jbosscmp-jdbc.xml, I get an error saying that there is no ejb-relationship-tag-name element. I do not know the reason for this, as I have followed the dtd for jbosscmp-jdbc.xml, and confirmed that the ejb-relationship-role-name tags match in both jbosscmp-jdbc.xml and ejb-jar.xml. Another modification I have tried is removing the relationships tag altogether from jbosscmp-jdbc.xml. This allowed me to deploy my beans. I also added the following cmp-field to the 'user' entity in jbosscmp-jdbc.xml: <cmp-field> <field-name>userTypeLocal</field-name> <column-name>UTL</column-name> <property-name>type</property-name> <column-name>user_type</column-name> <jdbc-type>VARCHAR</jdbc-type> <sql-type>VARCHAR(20)</sql-type> </cmp-field> This xml fragment is in jbosscmp.xml. The result of this is that there is a field called utl in the user_types table in the database. But the value being inserted into this field is not the foreign key integer id of the user_types table, but a serialized version of the UserTypeEJB. Thank you.
