Thanks again. Here is the snipper causing the cast error with jdbc41 pgsql driver

//code snippet -begin
dbConn = VCOSSDBUtils.getVCOSSDBConnection();                
dbConn.setAutoCommit(true);
Connection physicalDBConn = ((javax.sql.PooledConnection)dbConn).getConnection(); //get the real conn from the pooled conn
((org.postgresql.PGConnection)physicalDBConn).addDataType("type_customer_details_for_subscription", 
                        com.brillium.vcossPortalServer.datalayer.pgsql.udt.CreatedCustomerMVCAccountDetails.class);       
                ((org.postgresql.PGConnection)physicalDBConn).addDataType("type_mvc_plans_details", 
                        com.brillium.vcossPortalServer.datalayer.pgsql.udt.MVCPlanDetails.class);                  
                ((org.postgresql.PGConnection)physicalDBConn).addDataType("type_mvc_countries_map", 
                    com.brillium.vcossPortalServer.datalayer.pgsql.udt.CountryCodesMap.class); 
//code snippet - end

When I run, the exception occurs at first cat statement above!

The cast should work but while you wait for someone to confirm/comment you
might just try using the setTypeMap(...) method of the Jdbc4Connection

Supplying minimal code showing the problem might help too...
