Error while creating data source using Oracle Enterprise Manager 10g

Question

Hi,
I have deployed my web application developed on OC4J 9.0.4 stand alone (Win2K) to an integrated OC4J version(Solaris) using Oracle Enterprise Manager 10g.
However, I get an error when I try to create a data source.
The data source I want to create would have the following parameters (as seen in data-sources.xml on the stand alone version):
     <data-source
          class="com.evermind.sql.DriverManagerDataSource"
          name="TestDS"
          location="jdbc/OracleCoreDS"
          xa-location="jdbc/xa/OracleXADS"
          ejb-location="jdbc/TestDS"
          connection-driver="oracle.jdbc.driver.OracleDriver"
          url="jdbc:oracle:thin:@hostName:1521:test"
          username="user"
          password="password"
          min-connections="5"
          max-connections="20"          
          inactivity-timeout="30"
     />
When I entered the above data on the Enterprise Manager Data Sources page, I got the following error:
quote:
Error saving Data Source Properties. - Entity et="system";ei="0",et="application";ei="48",et="data-sources";ei="167":child:data-sourcechild key:location:jdbc/OracleCoreDS; class:com.evermind.sql.DriverManagerDataSource; already exists in the repository. Resolution: Please check the code base.

Could somebody tell me what I'm doing wrong ?
I tried to manually edit the data-sources.xml file but the data source didn't show up on the Enterprise Manager.
I'm using a new OC4J instance (on the Solaris machine) for my applications. Is the data source error related to this?
Any help will be greatly appreciated.
Thanks,
Shyam

Thanks for your reply , Steve.
I noticed that there is a default datasouce on the EM with the following parameters:
<data-source
          class="com.evermind.sql.DriverManagerDataSource"
          name="OracleDS"
          location="jdbc/OracleCoreDS"
          xa-location="jdbc/xa/OracleXADS"
          ejb-location="jdbc/OracleDS"
          connection-driver="oracle.jdbc.driver.OracleDriver"
          username="scott"
          password="->pwForScott"
          url="jdbc:oracle:thin:@localhost:1521:oracle"
          inactivity-timeout="30"
     />
The location and xa-location attributes that I use for my "test" data source are the same as the default one. So, could this be the issue?
What should be the values for location and xa-location attributes from my "test" data source?
Any help will be greatly appreciated.
Thanks,
Shyam
