SQL & PL/SQL

Hi All,
I have a problem with passing java object to procedure. Procedure is running properly when I execute in oracle,but it is not executing when I call from Java.
I am getting Error :
java.sql.SQLException: invalid name pattern: Pkg_Bulk_Insert.ITW_EMP_OBJ_ARRAY
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java)
at oracle.jdbc.oracore.OracleTypeADT.initMetadata(OracleTypeADT.java)
at oracle.jdbc.oracore.OracleTypeADT.init(OracleTypeADT.java)
at oracle.sql.ArrayDescriptor.initPickler(ArrayDescriptor.java)
at oracle.sql.ArrayDescriptor.<init>(ArrayDescriptor.java)
at oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java)
at JavaObjectToOracle.main(JavaObjectToOracle.java:31)


Here I am copying my procedure,oracle version is 9i.

Package specification:
CREATE OR REPLACE PACKAGE Pkg_Bulk_Insert AS
TYPE ITW_EMP_OBJ_ARRAY IS VARRAY(20) OF VARCHAR2(200);
PROCEDURE BULK_INSERT_TEST(strTable IN ITW_EMP_OBJ_ARRAY);
END Pkg_Bulk_Insert;
/

package body:

CREATE OR REPLACE PACKAGE BODY Pkg_Bulk_Insert AS
PROCEDURE BULK_INSERT_TEST(strTable IN ITW_EMP_OBJ_ARRAY) AS
i BINARY_INTEGER;
BEGIN
FORALL i IN 1..strTable.COUNT
INSERT INTO TEMP(NAME)
VALUES(strTable(i));
COMMIT;
END BULK_INSERT_TEST;
END Pkg_Bulk_Insert;
/

Here I am invoking the procedure:

DECLARE
x Pkg_Bulk_Insert.ITW_EMP_OBJ_ARRAY;
BEGIN
x := Pkg_Bulk_Insert.ITW_EMP_OBJ_ARRAY('A','B','C');
Pkg_Bulk_Insert.BULK_INSERT_TEST(x);
DBMS_OUTPUT.PUT_LINE('AFTER INSERTION');
END;

Please any body can help me on this regard.
