    Data source for relationship not found

    Jacques Buitendag Newbie

      Hi all

      I have been playing around with my JBoss 3.2.2 Server to see how much un-needed services I could remove.

      I have managed to remove a lot of services including Hypersonic.

      Hypersonic was bound to the JNDI tree as java:/DefaultDS

      But as I am using an other data source for JMS and persistence this was not a problem.

      My problem stared when I tried to deploy entity beans that had relationships between them, maintained by foreign keys.

      Each time I deployed the entity beans JBoss told me that it could not find the data source:


      javax.ejb.EJBException: Data source for relationship named A-B not found java:/DefaultDS

      I Know that no ware in my deployment descriptors I have told JBoss to use DefaultDS, I have created my own data source.

      When I removed DefaultDS as the default data source from the Server config I got null pointer exceptions when I tried to deploy the entity bean.


      I found references in the dtd for JBoss CMP 2 where you could specify the data source for relational tables but not for when you are using foreign key constraints.


      My Question is how do I solve this? So that my relations use the data source for the entity bean and not the default data source

      Kind Regards
