So, I've debugged deep into the JNDI SPI - and I've tracked the "null"
happening in orb.jboss.util.naming.NonSerializableFactory.
| public Object getObjectInstance(Object obj, Name name, Context nameCtx,
Hashtable env)
| throws Exception
| { // Get the nns value from the Reference obj and use it as the
map key
| Reference ref = (Reference) obj;
| RefAddr addr = ref.get("nns");
| String key = (String) addr.getContent(); // = java:/FluxMonClockerDS
| Object target = wrapperMap.get(key); // Return null
| return target;
| }
|
Seeing this I added a method breakpoint in the bind() method and restarted
JBoss.
The only breakpoint I got was for "java:/Mail".
So to check this, I changed the dsJndiName for the DatabaseServerLoginModule to
"java:/Mail".
Restarted and initiated a new login - and presto; ClassCastException instead of
NPE.
(noting that javax.mail.Session cannot be cast to javax.sql.Datasource).
So I presume this would be indicative of some fault in the JNDI configuration -
although I don't quite see why...?
