SetCustomDatum performance SQLJ team please respond

Question

I am facing performance overhead when using Jpub generated
classes for the object types.
I am using 817 jdbc and jpub but my database is 816. I have seen
that following statements each take around 2-3 seconds to
execute. Is there any communication between driver and database
to resolve the object type ?
I have found some posting regarding this but no solution. has
anyone here faced this problem ?
Please help.
cCallableStatement =
(OracleCallableStatement)m_cConnection.prepareCall("{call
list_unsync_appts_array(?,?,?,?,?,?,?,?)}");
((OracleCallableStatement)cCallableStatement).setCustomDatum
(1,ct_number_arr);
cCallableStatement.registerOutParameter
(2,OracleTypes.ARRAY,"T_EVENT_SUMMARY_ARR");
cCallableStatement.registerOutParameter
(3,OracleTypes.ARRAY,"T_EVENT_DETAIL_ARR");
cCallableStatement.registerOutParameter
(4,OracleTypes.ARRAY,"T_EVENT_SUMMARY_ARR");
cCallableStatement.registerOutParameter
(5,OracleTypes.ARRAY,"T_EVENT_DETAIL_ARR");
cCallableStatement.registerOutParameter
(6,OracleTypes.ARRAY,"T_EVENT_SUMMARY_ARR");
cCallableStatement.registerOutParameter
(7,OracleTypes.ARRAY,"T_ATTENDEE_EMAIL_ARR");
cCallableStatement.registerOutParameter
(8,OracleTypes.ARRAY,"T_ATTENDEE_EMAIL_ARR");
cCallableStatement.execute();

I retried this using the command line, as well as JDeveloper 3.1.1.2. It does not work.
Here are the specs:
Windows 2000
JDK 1.2.2
Oracle 8.1.6
JDBC & SQLJ 8.1.6 (comes with Oracle 8.1.6)
The package looks like this:
CREATE OR REPLACE PACKAGE qry IS
TYPE qry_results IS REF CURSOR;
FUNCTION get_all_appliances RETURN qry_results;
END qry;
Body looks like this:
CREATE OR REPLACE PACKAGE BODY qry IS
FUNCTION get_all_appliances RETURN qry_results IS
results qry_results;
BEGIN
OPEN results FOR
SELECT app_id, usr_app_name
FROM appliances
ORDER BY usr_app_name;
RETURN results;
END get_all_appliances;
END qry;
JPublisher does its thing, but it DOES NOT produce any output. It doesn't give any errors or anything, but it doesn't give any output files either.
I figure it must not be able to construct a SQL/J iterator? I don't know what's going on.
Please let me know if this is supposed to work or not? Is there anything in my code that should be changed to get it to work? Do I need to strongly type the REF CURSOR? The Jpub docs say it doesn't support strongly typed REF CURSORs.
Please advise, thanks in advance! Also please define whether this is unsupported or a bug.
