On using TestNG+Selenium , I'm not able to ensure the order of execution of classes.The order specified below (in testng.xml) is not working ->ClassTwo executes first and then ClassOne is executed. 

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="ABC" parallel="">
  <test verbose="2" name="xyz" annotations="JDK" preserve-order="true">
    <classes>
      <class name="script.ClassOne"/>
      <class name="script.ClassTwo"/>
    </classes>
  </test>
</suite>

How can I ensure that the order specified in TestNG.xml is retained?
