[GENERAL] JDBC - Call stored function that returns user defined type

[cyw]

I am looking for info on how to call a stored function that returns a user 
defined type.

Assume I have a type defined as:
    CREATE TYPE XYType AS (x int4, y int4);

and I use CYType in a function such as this:
    CREATE  FUNCTION test(IN z int4, OUT xy XYType, OUT status character) 
RETURNS RECORD AS $BODY$.....

I found info on how to formulate a CallableStatement, but no info on how to 
process the results from the call? Or does Postgres JDBC support this type of 
calls?

Any help is greatly appreciated.

Regards,
CYW
