In the deployment descriptor, where would I store database lookup names (JNDI name) for all EJBs?
I understand that each EJB has a resource-ref entry in DD which it can define resource JNDI name, but if all my EJBs point to the same Database, there ought to be a way globally defining that for ALL ejbs. I just do not know where that is in the DD.
Yan, As you know, you define the datasource on the server. So the real database info is in one place. As far as I know, you need to define the resource reference repeatedly though. In a way this makes sense because different beans could refer to the same datasource in different ways.
At first you should declare reference-ref in your DD. You put some logic resource name. For example 'jdbc/SystemDataSource'. When you deploy EJBs into some application server, you must have vendor-specific descriptor file (in JBoss it is 'jboss.xml'), where you must define exactly what 'jdbc/SystemDataSource' means - to what resources it refferers. In jboss.xml you can write it in 'resource-managers' section. For example:
