JDBC support for 8.1 OUT parameters

Hi,

Do you know where I can find Postgres JDBC driver that supports out
parameters? When I call my procedure, I'm getting:

org.postgresql.util.PSQLException: A CallableStatement function was
executed and the return was of type java.sql.Types=1111 however type
java.sql.Types=0 was registered.

I'm pretty sure the driver version I have
(postgresql-8.1-405.jdbc3.jar) supports OUT only on first parameter.
I've looked on the web but did not find anything. I saw a few patches,
but I wasn't sure if they were it.

CREATE OR REPLACE FUNCTION main.p_get_profile_simple(IN _profile_id
int8, OUT _main refcursor, OUT _lookingfor refcursor, OUT _purpose
refcursor) AS
....

CallableStatement stmt = null;
stmt = oCon.prepareCall("{ call main.p_get_profile_simple(?,?,?,?) }");
stmt.setLong(1, aMemberId);
stmt.registerOutParameter(2, Types.REF);
stmt.registerOutParameter(3, Types.REF);
stmt.registerOutParameter(4, Types.REF);

Regards,
Adam
