Oracle jdbc driver: sort order between letters and numbers

Question

Hello,
I am facing a very strange problem with sortering of data between letters and numbers.
I'am executing the following SQL request:
SELECT nummsg FROM CWD01 where nummsg = '00000001' or nummsg = 'AAAA0001' order by nummsg
When this request is executed with sqlplus or SQuirreL, I receive the expected result:
NUMMSG
00000001
AAAA0001
When I execute the following java code:
try {     String className = "oracle.jdbc.driver.OracleDriver";     Class driverObject = Class.forName(className);     Connection con = DriverManager.getConnection("myurl", "user", "pass");     Statement stmt = con.createStatement();     ResultSet rs = stmt.executeQuery(           "SELECT nummsg FROM CWD01 where nummsg = '00000001' or nummsg = 'AAAA0001' order by nummsg");     while (rs.next()) {           String x = rs.getString("nummsg");           System.out.println("nummsg " +x);     } } catch (Exception e) {     System.out.println("Failed: Driver Error: "+ e.getMessage()); }
I receive the unexpected result:
nummsg AAAA0001
nummsg 00000001
We are using the following version of Oracle:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bi
and the following jdbc driver:
Oracle Database 10g Release 2 (10.2.0.1.0) JDBC Drivers (ojdbc14.jar (1,536,979 bytes) - classes for use with JDK 1.4 and 1.5)
Any suggestion?

I checked, I'am sure of the problem:
package test;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
public class Test {
     public static void main(String[] args) {
          try {
               String className = "oracle.jdbc.driver.OracleDriver";
               Class driverObject = Class.forName(className);
               Connection con = DriverManager.getConnection("jdbc:oracle:thin:@<server>[:<1521>]:<database_name>", "user", "password");
               Statement stmt = con.createStatement();
               ResultSet rs = stmt.executeQuery(
                  "SELECT nummsg  FROM CWD01 where nummsg = '00000001' or nummsg = 'AAAA0001' order by nummsg");
               while (rs.next()) {
                    String x = rs.getString("nummsg");
                    System.out.println("nummsg " + x);
          } catch (Exception e) {
               System.out.println("Failed: Driver Error: " + e.getMessage());
}The table CWD01 defines the column NUMMSG as VARCHAR2(8).
The output gives:
nummsg AAAA0001
nummsg 00000001
