Re: Re: Inputs Appreciated - Calling pgsql stored proc with user defined sql types from java using pgsql-jdbc - Mailing list pgsql-jdbc

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...
