Calling a stored procedure with VARRAY as out parameter using JDBC

Question

Hi,
I want to use the data type VARRAY as an out parameter in an Oracle stored procedure. I want to call the stored procedure from
my java program using JDBC.
I'm using Oracle 8.1.5 for Windows NT.
Please help me.
Thanks

It's very similar to other datatype except that it uses OracleTypes.ARRAY typecode and the value is mapped to a oracle.sql.ARRAY instance. The code looks as follows --
cstmt.registerOutParameter (idx, OracleTypes.ARRAY, "VARRAY_TYPE_NAME_HERE");
cstmt.execute ();
ARRAY array = (ARRAY) cstmt.getObject (idx);
Thanks for your reply.
I have to use:-
OracleCallableStatement cs1 = (OracleCallableStatement )conn.prepareCall
( "{call proj_array(?)}" ) ;
for retrieving a collection as an OUT parameter.
This gives me the errors:-
C:\jdbc\VarraySQL.java:0: The method oracle.jdbc2.Blob getBlob(int) declared in class oracle.jdbc.driver.OracleCallableStatement cannot override the method of the same signature declared in interface java.sql.CallableStatement. They must have the same return type.
import java.sql.*;
^

import java.sql.*;

How do I get rid of these errors?
