I have managed to get a struts application using hibernate and C3P0 working on Tomcat 5. Im having trouble setting this up in OC4J 10.1.2 or OC4J 9.0.4 .

I get an exception in the OC4J's server.log:
05/07/06 16:25:20 Exception occured during Applications initialization: Unable to find DataSource of type com.mchange.v2.c3p0.ComboPooledDataSource

I have created a global datasource entry in OC4J. Here is my global data-sources.xml
<?xml version = '1.0' standalone = 'yes'?>
<!DOCTYPE data-sources PUBLIC "Orion data-sources" "http://xmlns.oracle.com/ias/dtds/data-sources-9_04.dtd">
<data-sources>
<data-source location="jdbc/employee_DS" class="com.mchange.v2.c3p0.ComboPooledDataSource" xa-location="jdbc/xa/employee_XADS" ejb-location="dbc/employeedb" connection-driver="oracle.jdbc.driver.OracleDriver" username="user" password="passwd1" url="jdbc:oracle:thin:@xserver:1521:db_test" inactivity-timeout="30" name="employee_DS"><description>Employee System Datasource</description></data-source>
</data-sources>

Can anyone shed light on how they used C3P0 and Hibernate to work on OC4J? Thanks.
