Oracle Connection Pool example server.xml

[Ryan Cornia]

I'm searching for an example server.xml that uses the Oracle connection pool mechanism 
from oracle. (As opposed to poolman, etc...)
 
Any help would be greatly appreciated, I cannot seem to get the server.xml correctly 
configured with the Oracle connection pool classes. 
 
What I've tried -
 
<Resource name="jdbc/timesheet" auth="Container" type="javax.sql.DataSource"/>
 
<ResourceParams name="jdbc/timesheet">
 <parameter>
   <parameter><name>user</name><value>my_username</value></parameter>
              <parameter><name>password</name><value>my_password</value></parameter>

  <name>factory</name>
  <value>oracle.jdbc.pool.OracleDataSourceFactory</value>
 </parameter>
 <parameter>
  <name>driverClassName</name>
  <value>oracle.jdbc.pool.OracleDataSource</value>
 </parameter>
 <parameter>
  <name>driverName</name>
  <value>jdbc:oracle:thin:@MYHOST:1521:ORCL</value>
 </parameter>
</ResourceParams> 

When I try and get a connection from the pool, it returns null. If I configure it to 
not use a connection pool, the code works, so I know the problem is with the oracle 
pool definition.
 
Thanks,
Ryan
