Sessions.xml data source not working using toplink

Question

I'm having some difficulty getting a data source to work. I have an ADF selectOneChoice component and I want the list of values available to be bound to a database given by the JNDI name and controlled at the j2ee container level.
I have created a sessions.xml file
<toplink-configuration>
<session>
<name>PIMSSession</name>
<project-xml>META-INF/PIMS_ADF_TLMap.xml</project-xml>
<session-type>
<server-session/>
</session-type>
<login>
<datasource>jdbc/PIMSDS</datasource>
<uses-external-connection-pool>true</uses-external-connection-pool>
</login>
<connection-pool>
<is-read-connection-pool>true</is-read-connection-pool>
<name>default</name>
<login>
<datasource>jdbc/PIMSDS</datasource>
<platform-class>Oracle10g</platform-class>
<uses-external-connection-pool>true</uses-external-connection-pool>
</login>
</connection-pool>
</session>
</toplink-configuration>
The sessions.xml points to the toplink mapping file PIMS_ADF_TLMap.xml, which contains information about the database view that is used to populate the drop down list. It also contains a deployment connection:
<toplink:login xsi:type="toplink:database-login">
<toplink:platform-class>oracle.toplink.platform.database.oracle.Oracle10Platform</toplink:platform-class>
<toplink:user-name>pimsdev</toplink:user-name>
<toplink:password>BB742416276274A494F7008B3AE0FB10</toplink:password>
<toplink:driver-class>oracle.jdbc.OracleDriver</toplink:driver-class>
<toplink:connection-url>jdbc:oracle:thin:@yvworad01:1521:PIMSD</toplink:connection-url>
</toplink:login>
The problem I'm having is that my ADF application always binds the selectOneChoice to the connection-url in the toplink mapping file instead of the datasource in the sessions.xml.
If I remove the deployment connection from the mwp file, recompile and deploy I get a JBO-29000 error about not having a suitable driver.
Does anyone know how to get the selectOneChoice to bind to a datasource instead of the toplink mapping connection-url?

Hi Aaakar,
From the error message, please try to change the setting of Credential type for the data source on report manager as follows:
Go to the Data Sources properties page.
For the Connect Using option, select Credentials stored securely in the report server.
In User Name and Password, type credentials that can be used to access the database. If you are using SQL Server as the data source, the user name must be valid for both logging on to the server and for accessing the database that contains the data for
the report.
If the user name and password are credentials for a Windows account, select Use as Windows Credentials.
If you want the report server to pass the credentials of the user accessing the report to the server hosting the external data source, click Windows Integrated Security. In this case, the user is not prompted to type a user name or password.

Hope this helps.
