Need a substitue for OrionPooledDataSource **ClassCastException **

Question

Hi
we are getting a "null, java.lang.ClassCastException" when executing the following:
InitialContext ic = new InitialContext();
Object o = ic.lookup("jdbc/od_jdbc_connectionPooledDS");
OracleConnectionPoolDataSource ds = (OracleConnectionPoolDataSource) o;
even though my data-sources.xml in my
C:\JDev\jdev\mywork\DVDOrdering\DVDOrdering-data-sources.xml
contains the following
<data-source name="jdev-connection-od_jdbc_connection"
class="com.evermind.sql.DriverManagerDataSource"
location="jdbc/od_jdbc_connectionCoreDS"
xa-location="jdbc/xa/od_jdbc_connectionXADS"
ejb-location="jdbc/od_jdbc_connectionDS"
pooled-location="jdbc/od_jdbc_connectionPooledDS"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="hr" password="hr"
url="jdbc:oracle:thin:@localhost:1521:Metadata" inactivity-timeout="30"/>
Thru the debugger i can see that o is of type OrionPooledDataSource
What package / class else can i cast the datasource to?
All the best
Jim

Answer 1

Thru the debugger i can see that o is of type OrionPooledDataSourceHm,,, this Orion thing must have faded away from oracle jdbc packages some time ago.
Anyway, you can probably cast it to javax.sql.ConnectionPoolDataSource. You can check it by reflection         Class orionDs = OrionPoolDataSource.class;
        Class[] ifs = orionDs.getInterfaces();
        for ( int i =0; i< ifs.length; i++) {
            System.out.println(ifs.getName());
System.out.println(orion.Ds.getSuperClass.getName());
What is better, if you use Jdeveloper, right click the object and choose "view Type Hierachy". You can see them all.
