JNDI setup problems

[Bonnie MacKellar <BM...@mobius.com>]

OK, I have decided that my problems must be with the way I am specifying
JNDI lookup in the repository_database.xml file.

Here are the steps I have tried so far :
In weblogic, I create a pooled DataSource whose JNDI name is OJBDataSource.
I verify that this works using a straight JDBC lookup.

I then create this entry in the repository_database.xml file :

   <!-- Datasource example -->
    <!-- jdbc-connection-descriptor
        jcd-alias="testOJB"
        default-connection="true"
   		platform="MsSqlServer"
   		jdbc-level="2.0"
   		jndi-datasource-name="OJBDataSource"
   		username="admin"
   		password="ActiveBill"
		eager-release="false"
        batch-mode="false"
        useAutoCommit="0"
        ignoreAutoCommitExceptions="false"
   >
        <sequence-manager
className="org.apache.ojb.broker.util.sequence.SequenceManagerNextValImpl">
            <attribute attribute-name="grabSize" attribute-value="20"/>
        </sequence-manager>

   </jdbc-connection-descriptor -->

and I have these entries in ojb.properties (I think these are the relevant
ones) :

----------------------------------------------------------------------------
ConnectionFactoryClass=org.apache.ojb.broker.accesslayer.ConnectionFactoryPo
oledImpl

ConnectionManagerClass=org.apache.ojb.broker.accesslayer.ConnectionManagerIm
pl

OJBTxManagerClass=org.apache.ojb.odmg.LocalTxManager
----------------------------------------------------------------------------

I have verified that the correct repository.xml and ojb.properties files are
actually being used. I have also tried different means of specifying the
Broker, most currently by this call :

------------------------------------------------------------------
broker = PersistenceBrokerFactory. 
                     createPersistenceBroker(new
PBKey("testOJB","admin","ActiveBill")); 
-----------------------------------------------------------------
The user name and password which I am passing are the Weblogic ones, not the
MsSQLServer ones. I did try using the MsSQLServer ones, to no avail.

The error message that I get is

----------------------------------------------------------------

Obviously, I am doing something wrong. But what? I cannot find the problem.
I have tried many different possibilities.
