Lookup DataSource: NameNotFoundException

Question

I am having a terrible time looking up a data source. I always get a NameNotFoundException.
Here is what I've got:
WEB.XML
<resource-ref>
     <res-ref-name>impresaDataSource</res-ref-name>
     <res-type>javax.sql.DataSource</res-type>
<res-auth>CONTAINER</res-auth>
</resource-ref>
WEBLOGIC.XML
<reference-descriptor>
     <resource-description>
          <res-ref-name>impresaDataSource</res-ref-name>
          <jndi-name>jdbc/impresaDataSource</jndi-name>
     </resource-description>
</reference-descriptor>
CONFIG.XML
<JDBCConnectionPool CapacityIncrement="5"
DriverName="oracle.jdbc.driver.OracleDriver"
InitialCapacity="5"
MaxCapacity="50" Name="impresaPool"
Password="{3DES}vWu5VQp5y9k=" Properties="user=world"
Targets="impresa-server"
URL="jdbc:oracle:thin:@orion:1521:devl7"/>
<JDBCDataSource JNDIName="jdbc/impresaDataSource"
Name="impresaDataSource" PoolName="impresaPool"
RowPrefetchEnabled="false" Targets="impresa-server"/>
THE CODE:
Properties props = new Properties();
IntialContext ctx = new InitialContext(props);
DataSource ds = ctx.lookup("impresaDataSource");
I've tried everything I can think of, but nothing seems to work. Another thread
from about a year ago suggested adding the following properties to the connection
pool:
dll=ocijdbc8;protocol=thin
But that did not work either.
Any ideas?

I would say it must be: java:comp/env/jdbc/impresaDataSource
