Error saving Data Source Properties. - Base Exception. Call Oracle Support

Question

Hi,
Oracle Application Server 10g Release 2 (10.1.2).
I tried to create new Datasource using OEM Console but it throws error as following :
Error saving Data Source Properties. - Base Exception: The Entity et="system";ei="0",et="application";ei="138",et="data-sources";ei="146":child:data-sourcechild key:location:jdbc/OracleCoreDS; class:com.evermind.sql.DriverManagerDataSource; already exists in the repository. Resolution: If possible, remove et="system";ei="0",et="application";ei="138",et="data-sources";ei="146":child:data-sourcechild key:location:jdbc/OracleCoreDS; class:com.evermind.sql.DriverManagerDataSource; . Call Oracle Support.
May I know how to resolve this please ?
Thank you.
J.

Hi ,
Write following code in your UDF
String Query = " ";
Channel channel = null;
DataBaseAccessor accessor = null;
DataBaseResult resultSet = null;
Query = <your query>;
try{
         channel =LookupService.getChannel(<comm channel name>,< business system>);
         accessor = LookupService.getDataBaseAccessor(channel);
         resultSet = accessor.execute(Query);
         if(!(resultSet.equals(null)))
                   Iterator rows = resultSet.getRows();
                   if (rows.hasNext())  {        
                   Map rowMap = (Map)rows.next();
                   <your variable>.add(rowMap.get(<db field name>)+ "");
catch(Exception ex)
      result.addValue(ex.getMessage());
finally
          try
     if (accessor!=null) accessor.close();
          catch(Exception e)
     result.addValue(e.getMessage());
