Can anyone help me in a problem with PL/SQL Tables & the Java getArray()

Question

The problem is the following:
I would tike to get a PL/SQL Table (a table of varchar2) into a Java String Array.
It works very well except that instead of getting the characters in the PL/SQL Table
I receive the character codes in each string.
In the following example i should get:
spring
summer
outumn
winter
Instead I get:
0x737072696E67
0x73756D6D6572
0x6F7574756D6E
0x77696E746572
Steps to try the sample
1)Creating the following type
create or replace TYPE CHAR_ARRAY IS TABLE OF VARCHAR(32767);
2)Creating the following stored procedure
create or replace PROCEDURE MQ_MSG_PROCESSOR
   MessageText in VARCHAR2,
   QueueName out VARCHAR2,
   RplyMessage out CHAR_ARRAY,
   HastoCommit out NUMBER
AS
   RMessage CHAR_ARRAY;
BEGIN
   QueueName:='DEV_OUT';
   RMessage:=CHAR_ARRAY();
   RMessage.Extend(4);
   RMessage(1):='spring';
   RMessage(2):='summer';
   RMessage(3):='outumn';
   RMessage(4):='winter';
   HastoCommit:=1;
   RplyMessage:=RMessage;
END;
3)Copiling and running the following java class
import java.sql.*;
import oracle.sql.*;
import oracle.jdbc.oracore.Util;
import oracle.jdbc.driver.*;
import java.util.Dictionary;
public class ArrayExample
   public static void main (String args[]) throws Exception
      MSG Msg=null;
      oracle.sql.ARRAY RMsg=null;
      DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
      Connection conn = DriverManager.getConnection ("jdbc:oracle:oci8:@test","test", "test");
      conn.setAutoCommit (false);
      try
         String []array={};
         ArrayDescriptor desc=ArrayDescriptor.createDescriptor("CHAR_ARRAY",conn);
         ARRAY CHAR_ARRAY=new ARRAY(desc,conn,array);
         OracleCallableStatement sproc = (OracleCallableStatement)conn.prepareCall("{call GSM.MQ_TST.MQ_MSG_PROCESSOR(?, ?, ?, ?)}");
         sproc.setString(1, "hello"); //MessageText
         sproc.registerOutParameter(2, OracleTypes.VARCHAR);   //QueueName
         sproc.registerOutParameter(3, OracleTypes.ARRAY,"CHAR_ARRAY");   //RplyMessage
         sproc.registerOutParameter(4, OracleTypes.NUMBER);      //HastoCommit
         sproc.execute();
         CHAR_ARRAY=(oracle.sql.ARRAY)sproc.getARRAY(3);
         array = (String [])CHAR_ARRAY.getArray();
         for(int i=0;i<array.length;i++)
            System.out.println(array);
      catch(SQLException e)
         System.out.println("Error while trying to execute MQ_MSG_PROCESSOR");
         System.out.println(e);
      conn.close();

Hi,
I tried the code with same procedure.
That works out fine for me..
and it prints out exactly the same words as you mentioned..:))
may be you must have changed something later on.. which started printing character codes..
but for me it works perfectly fine..
All The Best..
