Passisng array from Java into PL/SQL procedure

Question

Hi everybody!
I have type created with :
CREATE OR REPLACE TYPE my_type IS TABLE OF number;
Next I have procedure withinin a package which has parameters:
PROCEDURE my_proc
(p_Result OUT NUMBER,
p_Id table.column%TYPE,
p_MyType my_type
I call this procedure from Java :
import javax.sql.*;
import java.sql.*;
import oracle.jdbc.*;
import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;
public class MyClass extends QueryClient {
private int Id;
private int type;
private Integer[] List;
private int result;
public MyClass(int Id, eType type,
Integer[] List) throws SQLException {
this.Id = Id;
this.type = (type.equals(eType.TYPE_EXPORT) ? 1 : 0);
this.List = List;
this.execute("{call my_package.my_proc(?,?,?,?)}");
public void body(CallableStatement stmt) throws SQLException {
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor("MY_USER.MY_TYPE", getCon());
ARRAY array_to_pass = new ARRAY(descriptor, getCon(), this.List);
// register the type.
stmt.registerOutParameter(1, OracleTypes.NUMBER); // result of procedure calling
stmt.setInt(2, this.Id );
stmt.setInt(3, this.type);
stmt.setArray(4, array_to_pass);
// execute and retrieve the result set
stmt.execute();
this.result = stmt.getInt(1);
public int getResult() {
return result;
EVERYTHING WORKS FINE, BUT when I move type "my_type" into package header
TYPE my_type IS TABLE OF number;
I receive error after calling procedure
java.sql.SQLException: invalid name pattern: MY_USER.MY_TYPE
I dropped type my_type after moving it into package. So there is only one my_type, in the package.
User who call procedure is owner of the package.
So questions are:
1. Is it possible to have my_type within package without error?
2. Is it possible to describe my_type without having a connection to database? My aim is eliminate number of connections to database.
Thanks all.
Matus.

You can't use the packaged type for this. You need to use the original collection type (i.e. via the CREATE TYPE syntax) as you have discovered yourself.
