Clearly, its better to have TNS set up properly.

My question is why am I getting the following exception when jboss 4.0.4 is restarted or when I redeploy the application:
org.jboss.deployment.DeploymentException: Error during deploy; - nested throwable: (javax.naming.NamingException: resource-ref: DCDEV has no valid JNDI binding. Check the jboss-web/resource-ref.)
NOTE: The application is an exploded(unpacked) format. Not sure if i'm using the correct technical wording.

[JBoss Seam] - one2many example
by wondermike
Hello,
I'm looking for a One2Many example which is just good enough for a beginner like me ... i.e. not too complicated ;-) I've looked at the issues example, but I could not simplify it for my purposes, it didn't work - the editor stuff killed me.
In the end I'd like to descent several hierarchical layers like
* client1
* client1-contract1
* client1-contract2
* client1-contract2-contractdetail1
* client1-contract2-contractdetail2
* client1-contract2-contractdetail3
...
* client2
* client3
...
having 3 entities: clients, contracts and contractdetails
and 3 different pages listing each m clients, n contracts and so on ...
Can you help with with a simple example or a pointer to an example?
The interesting thing for me is the logical transfer of the @DataModelSelection to the next hierarchical layer which would be included in the where clause of the next layer's 'entityManager.createQuery("from ...' I think the next layer receives the Selection via injection but I'd like to see a whole working example.
TIA!
Michael
