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