Using EJB 2.1, I have 2 CMP Entities persisted on 2 different datasources. Now I want to create a unidirectional many-to-one relationship where the many side sees the one side and the one side is blind. But, I get an EJBException wrapping an SQL error: | javax.ejb.EJBException: Load relation failed; CausedByException is: | ORA-00942: table or view does not exist | I suspect from reading the JDBCCMRFieldBridge class that JBoss is using the datasource of one side to access the other side. Here is the JDBCCMRFieldBridge code: | // Data Source | if(metadata.getRelationMetaData().isTableMappingStyle()) | { | dataSource = metadata.getRelationMetaData().getDataSource(); | } | else | { | dataSource = hasForeignKey() ? entity.getDataSource() : relatedEntity.getDataSource(); | } | It seems like the choice of datasource is based on having a foreign key or not. How can I define a relationship without foreign keys? Using xdoclet I defined the relationships this way, using target-XXXX to define the blind side of the relationship | * @ejb.relation | * name="Order-Security" | * role-name="many-Orders-belong-to-one-Security" | * target-role-name="one-Security-has-multiple-Orders" | * target-ejb="Security" | * target-multiple="yes" | * | * @jboss.relation | * fk-constaint="false" | * fk-column="SECURITY_ID" | * related-pk-field="securityId" | First of all, is CMR over different datasources supported in EJB 2.1? If not, does JBoss offer a work around? PS: Both entity beans work stand alone. I can execute create and finder method on them. I'm using JBoss 4.0.3SP1.
