Accessing ORACLE's VARRAY using JDBC

Question

Hi,
I have a created a VARRAY type like following in ORACLE:
CREATE OR REPLACE
TYPE opr_typ_attrib_val_arr AS TABLE OF VARCHAR2 (255)
I am trying to access this VARRAY using the following java code:
ArrayDescriptor arrayDesc = ArrayDescriptor.createDescriptor("opr_typ_attrib_val_arr ", (OracleConnection)connection);
String arrayValues[] = {"123", "234"};
ARRAY array = new ARRAY(arrayDesc, connection, arrayValues);
But in the very first statement, where I am getting the object of ArrayDescriptor, I am getting the java.lang.ClassCastException exception.
I am using oracle type 4 thin driver. And the above mentioned code I have written in EJB.
"connection" is a valid connection object.
Could anybody help me out to resolve this issue.
Thanks in advance.

Hi,
With a snap shot of your code it would hv been more easier to pinpoint your problem.
However this is how I am doing it:
(the thin driver, classes12.zip must be in the classpath)
--In the Oracle PL/SLQ proc:
type REC_TYPE is ref cursor;
FUNCTION spFindBid(
p_ORDCreateSeq in number,
p_RAT in number,
p_prdID in number,
p_ACCTID in number,
p_LAMT in number) return REC_TYPE
IS
rc REC_TYPE;
begin
open rc for
SELECT * from table_name
return rc;
// in the Java code:
import oracle.jdbc.driver.*;
//besides other imports.
CallableStatement cs
= cn.prepareCall("{? =....}");
cs.registerOutParameter(1,
OracleTypes.CURSOR);
cs.setString(1, "XXXX");
cs.execute();
java.sql.ResultSet rs =
(java.sql.ResultSet)cs.getObject(1);
//this will return a standard resultSet,
//as what is recvd when we execute a
//SELECT via standard, CreateStatement()....
//loop on it while(rs.next()) to get
//the dataI am using the 100% Java thin driver.
I could not figure how to use an OCI 8 driver
with a Standalone Java program (not weblogic). Could not find a driver as a(.zip/.jar) file. OCI8 has more easier ways of accessing OracleDB.
