ok, i tried but clearly i'm making some mistake. i tried to define a CMR field for entity Document that references "many" accounts, and i added in both bean and localhome interface the getters and setters for this CMR field named "account" in the <ejb-relation>.
I also added the block into jbosscmp-jdbc.xml and a join query. Here's the code: ejb-jar.xml | [...] | <entity > | <description><![CDATA[Description for Dipartimento]]></description> | <display-name>Name for Dipartimento</display-name> | | <ejb-name>Dipartimento</ejb-name> | | <local-home>servizioDipartimentale.interfaces.DipartimentoLocalHome</local-home> | <local>servizioDipartimentale.interfaces.DipartimentoLocal</local> | | <ejb-class>servizioDipartimentale.ejb.DipartimentoBean</ejb-class> | <persistence-type>Container</persistence-type> | <prim-key-class>java.lang.Integer</prim-key-class> | <reentrant>False</reentrant> | <cmp-version>2.x</cmp-version> | <abstract-schema-name>Dipartimento</abstract-schema-name> | <cmp-field > | <description><![CDATA[Getter for CMP Field idDipartimento]]></description> | <field-name>IdDipartimento</field-name> | </cmp-field> | <cmp-field > | <description><![CDATA[Getter for CMP Field Descrizione]]></description> | <field-name>Descrizione</field-name> | </cmp-field> | <primkey-field>IdDipartimento</primkey-field> | | <query> | <query-method> | <method-name>findAll</method-name> | <method-params> | </method-params> | </query-method> | <ejb-ql><![CDATA[SELECT OBJECT(a) FROM Dipartimento AS a]]></ejb-ql> | </query> | | <query> | <query-method> | <method-name>findRelatedAccounts</method-name> | <method-params></method-params> | </query-method> | <ejb-ql><![CDATA[SELECT OBJECT(a) FROM Dipartimento AS d, IN (d.Accounts) as a WHERE d.descrizione = 'DIPARTIMENTO DI FISICA']]></ejb-ql> | <!-- ejb-ql><![CDATA[SELECT OBJECT(a) FROM Account AS a WHERE a.Dipartimento.Descrizione = 'DIPARTIMENTO DI FISICA']]></ejb-ql--> | </query> | </entity> | [...] | <relationships> | | <ejb-relation> | <ejb-relation-name>Dipartimento-Account</ejb-relation-name> | <ejb-relationship-role> | <ejb-relationship-role-name>Department-has-accounts</ejb-relationship-role-name> | <multiplicity>One</multiplicity> | <relationship-role-source> | <ejb-name>Dipartimento</ejb-name> | </relationship-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-belongs-to-department</ejb-relationship-role-name> | <multiplicity>Many</multiplicity> | <cascade-delete/> | <relationship-role-source> | <ejb-name>Account</ejb-name> | </relationship-role-source> | </ejb-relationship-role> | </ejb-relation> | jbosscmp-jdbc.xml | [...] | <entity> | <ejb-name>Dipartimento</ejb-name> | <create-table>true</create-table> | <remove-table>true</remove-table> | <table-name>DIPARTIMENTO</table-name> | | <cmp-field><field-name>idDipartimento</field-name></cmp-field> | <cmp-field><field-name>descrizione</field-name></cmp-field> | | </entity> | [...] | <relationships> | <ejb-relation> | <ejb-relation-name>Dipartimento-Account</ejb-relation-name> | <foreign-key-mapping/> | | <ejb-relationship-role> | <ejb-relationship-role-name>Department-has-accounts</ejb-relationship-role-name> | <key-fields/> | </ejb-relationship-role> | | <ejb-relationship-role> | <ejb-relationship-role-name>Account-belongs-to-department</ejb-relationship-role-name> | <key-fields> | <key-field> | <field-name>dipartimento</field-name> | <column-name>idDocumento</column-name> | </key-field> | </key-fields> | </ejb-relationship-role> | </ejb-relation> | and the error trying to deploy the application: Finder findRelatedAccounts defined on Dipartimento should return only instances of Dipartimento but the query results in instances of Account so should i put it in Account bean? but then the relationship? how to change it in bidirectional way?
