How to create Array type parameter of Oracle 10.2.0.1.0 in java

Question

I create a collection type with:
CREATE OR REPLACE
type TEST_User.T_ARRAY AS TABLE OF VARCHAR2(100);
and in java code, I use following code to create a parameter of this type, and set it for a procdure
String[] userMakeArray = new String[]{"V", "N", "A"};
oracle.sql.ArrayDescriptor descriptor = oracle.sql.ArrayDescriptor.createDescriptor("TEST_User.T_ARRAY", cn); // cn is connection instance to database
oracle.sql.ARRAY array = new oracle.sql.ARRAY(descriptor, cn, userMakeArray);
((oracle.jdbc.OracleCallableStatement)call).setArray(8, array);
when i use this to call procedure in Oracle 10.1, it work well.
In Oracle 10.2, it does not work well.
For test, I can execute procedure well in sql plus, but in java client, I found that array contains three items "Null", while array is correct when conect to 10.1 enviroment.
does anybody know what's the reason for this.
thanks a lot.

Hi,
Too long to copy/paste here but i have a simpler working example of Nested Table of VARCHAR2 type against 10.2.0.x, in chapter 3 and 8 of my book:
create or replace type NTab_Vc2 as TABLE of varchar2(30)
create table NSTableTab (id int, numnt NTab_Num, vc2nt NTab_Vc2, datnt
NTab_Dat)
nested table numnt store as NSTabNum,
nested table vc2nt store as NSTabVc2,
nested table datnt store as NSTabDat;
insert into NSTableTab values (1,
NTab_Num(1, 2, 3, 4, 5, 6, 7, 8, 9, 10),
NTab_Vc2 ('One', 'Two', 'Three', 'Four', 'Five', 'Six', 'Seven', 'Eight', 'Nine', 'Ten'),NTab_Dat('01-JAN-2003', '02-JAN-2003', '03-JAN-2003', '04-JAN-2003',
'05-JAN-2003', '06-JAN-2003', '07-JAN-2003', '08-JAN-2003',
'09-JAN-2003', '10-JAN-2003')
// The following code snippet retrieves and returns a
// NTab_Vc2 as a java.sql.Array
OraclePreparedStatement ps = (OraclePreparedStatement)
conn.prepareStatement ("SELECT VC2NT FROM NSTableTab
WHERE ID = ?");
ps.setNUMBER (1, id[0]);
OracleResultSet rs = (OracleResultSet) ps.executeQuery();
Array a = null;
while (rs.next())
a = (Array) rs.getObject(1);
ps.close();
return a;
