Problem calling Stored Procedure returning SETOF UDT (Using Spring)

Question

I am using Spring's StoredProcedure class to call a stored procedure from a PostgreSql database. It returns a set of user defined data types. I'm having a problem in parsing the results returned.
The user defined data type :
CREATE TYPE process_states AS (
process_name text,
process_type text
The stored procedure returns a SET of "process_state" :
CREATE FUNTION inquire_process_state (.....)
RETURNS SETOF process_state AS '
SELECT ....
I hava a Java class extending the Spring StoredProcedure classs.
public MyProcStats extends StoredProcedure {
private class ProcStateCallBackHandler implements RowCallBackHandler {
public void processRow(ResultSet rs) throws SQLException {
System.out.println(rs.getString(1));
public MyProcStats (DataSource ds) {
super(ds, "inquire_process_state");
super.setFunction(true);
declareParameter(new SqlOutparameter("rs", Types.OTHER, new ProcStateCallBackHandler());
declareParameter(new SqlParameter("family_name", Types.VARCHAR) ;
While testing this class, I get an errormessage
"java.sql.SQLException:ERROR: cannot display a value of type record"
I would appreciate if anyone can point out my mistakes. I tried declaring
new SqlOutParameter("rs", Types.OTHER, "process_state"), but that didn't help.

As the related posts suggest, you will need to use direct JDBC code for this.
Also I'm not sure JDBC supports the RECORD type, so you may need to wrap your stored functions with ones that either flatten the record out, or take OBJECT types.
