ClassCastException with Oracle Type2 Driver

Question

Hi,
I am trying to configure Connection pool to Oracle 8.1.7 database using Type2 drivers. I did the following :-
1) Server1 -> JDBC -> ConnectionPools -> New
2) Select Oracle 8.1.x database
3) The next page shows Datasource name as : oracle.jdbc.pool.OracleDataSource
4) Entered the appropriate user name, pwd, host, port etc in the properties
5) Created JDBC resource with a JNDI name as "foundation"
6) Saved & restarted the server
Now, I have the following code in the DBConnection class:-
Line 1 - InitialContext ctx = new InitialContext();     
Line 2 - ds = (DataSource) ctx.lookup("foundation");
Line 3 - Connection conn = ds.getConnection();
line 3 is failing with ClassCastException: com.sun.enterprise.resource.JdbcDataSource
BTW, I am accessing this DBConnection class from a Stateless Session bean to get the java.sql.Connection. I did not do any special configuration (like <resource-ref>) in the configuration xml files.
I am totally clueless about what could be the reason for this exception. I could not find any help in the user groups / forums. Any help is appreciated.
Thanks in Advance,

Hi Parsuram,
Thanks for the response. I am creating java.sql.Connection - I have explicitly qualified the connection object as java.sql.Connection. But, still I get the error:
java.lang.ClassCastException: com.sun.enterprise.resource.JdbcDataSource
Note: The class name in exception is not com.sun.enterprise.resource.JdbcDataSource.Connection
My server configuration is as follows :-
<jdbc-resource enabled="true" pool-name="foundation" jndi-name="foundation"/>
<jdbc-connection-pool steady-pool-size="8" max-pool-size="32" max-wait-time-in-millis="60000" pool-resize-quantity="2" idle-timeout-in-seconds="300" is-isolation-level-guaranteed="false" is-connection-validation-required="false" connection-validation-method="auto-commit" fail-all-connections="false" datasource-classname="oracle.jdbc.pool.OracleDataSource" name="foundation">
<property value="192.168.0.12" name="serverName"/>
<property value="1521" name="portNumber"/>
<property value="foundation" name="user"/>
<property value="foundation" name="password"/>
<property value="ORCL" name="databaseName"/>
</jdbc-connection-pool>
</resources>
Appreciate your help,
