Problem of oo4o insert varray data

Question

i want to use oracle oo4o to insert the varray type data ，but it occurs error that
OIP-04149: Invalid input object for field and parameters
who will tell me what's wrong for this programm
the table is created by the follow sql:
drop table Varr_test;
CREATE TYPE varrayf_9 AS VARRAY(9) OF float;
CREATE TABLE Varr_test
NUM_INDEX number NOT NULL,
TEXT varchar2(128),
NUMBER_OPT varrayf_9
programme as follows：
OStartup();
oresult oRes ; // oRes is oresult
OSession m_o_Session; //
ODatabase m_o_db; //
oRes = m_o_Session.Open();
oRes = m_o_db.Open(m_o_Session,"oraDemet","system","myora"); // m_o_db is ODatabase
oRes = m_o_db.BeginTrans();
// the insert proccess
// Add Params
OParameterCollection oParamCol = m_o_db.GetParameters();
OParamArray o_NUM_INDEX_Ary = oParamCol.AddTable("B_NUM_INDEX",OPARAMETER_INVAR,OTYPE_NUMBER,10);
OParamArray o_TEXT_Ary = oParamCol.AddTable("B_TEXT",OPARAMETER_INVAR,OTYPE_VARCHAR2,10,250);
OParamArray o_NUMBER_OPT_Ary = oParamCol.AddTable("B_NUMBER_OPT",OPARAMETER_INVAR,OTYPE_VARRAY,10);
OCollection otest;
for(int i =0;i<10;i++){
o_NUM_INDEX_Ary.SetValue(i,i);
o_TEXT_Ary.SetValue("test",i);
otest.Open(m_o_db,"varrayf_9");
for(int j=0;j<9;j++)
otest.SetValue(j+1,j+1);
if (oRes != OSUCCESS)
{   // couldn’t create the table
AfxMessageBox(m_o_db.GetErrorText());
o_NUMBER_OPT_Ary.SetValue(otest,i);
oRes = m_o_db.ExecuteSQL("INSERT INTO Varr_test (NUM_INDEX,TEXT,NUMBER_OPT) VALUES (:B_NUM_INDEX,:B_TEXT,:B_NUMBER_OPT)");
if (oRes != OSUCCESS)
{   // couldn’t create the table
AfxMessageBox(m_o_db.GetErrorText());
oParamCol.Remove("B_NUM_INDEX");
oParamCol.Remove("B_TEXT");
oParamCol.Remove("B_NUMBER_OPT");
oRes = m_o_db.CommitTrans();
oRes = m_o_db.Close();
m_o_Session.Close();
OShutdown();

Hi,
I have stored Unicode arabic Data correctly using UNISTR function in SQLPLUS but on select it doesnot display the arabic characters correctly which is ok. Since i can see the arabic data using iSQLPlus.
Using SQL Plus I tried this
insert into amc (amc_id,name) values('sqlplus1',unistr('\0642'));
In SQL Plus
select amc_id, name, dump(name,1016) from amc;
AMC_ID NAME DUMP(NAME,1016)
-sqlplus1 Þ Typ=1 Len=2 CharacterSet=AL16UTF16: 6,42
Although \u0642 is defined in codepage 1256 as arabic letter "Qaf" but sql plus is showing this Þ which is not define in 1256. Dont know why.
In iSQLPLus Its showing correctly
sqlplus1 ق Typ=1 Len=2 CharacterSet=AL16UTF16: 6,42
My actual problem is storing/retrieving data with JAVA. Java client is displaying above stored value "qaf" as ¿ . why?
On Storing i apparently losing first byte.Using java i tried to insert the another value using this code.
String uniname = "\u06A7";
String qry=
"insert into fms_save.amc " +
"(amc_id,element_type_id, amc_short_name, transaction_id, transaction_year, name, last_accessed_date, post_action) " +
" values " +
"('client92','A','clinet1',11,2007,UNISTR('" + uniname + "'),sysdate,'NSAVE')";
PreparedStatement pstmt = c.prepareStatement(qry);
pstmt.executeUpdate();
select result in both sql plus and isqlplus is as follow
AMC_ID NAME DUMP(NAME,1016)
client92 § Typ=1 Len=2 CharacterSet=AL16UTF16: 0,a7
Please notice the DUMP. Why first byte 06 is not storing in the db. Its only storing second byte A7.
I understand that System is displaying A7 as § whose codepage value is 00A7 in windows charset 1256 But i wonder why first byte data 06 is getting lost?
I am not using OracleStatement setFormOfUse(..) instead i am using Java System Property -Doracle.jdbc.defaultNChar=true also i am using
-Doracle.jdbc.convertNcharLiterals="true" to avoid NChar String literal data lost.
Can you please help me to get my Java working with Arabic storage and retrival?
Thanks in advance.
