title: What's wrong about request.getSession().setAttribute()
body: <p>I use to pass data between <code>*.java</code> and <code>*.jsp</code>, since this is a MVC framework, it will go by the <code>*.java</code> first. so i used <code>request.getSession().setAttribute("test", "01010101010")</code> to save the value, and then in <code>*.jsp</code>, use <code>request.getSession().getAttribute("test")</code> to get value.
  But it returns a strange string <code>"682342348"</code> all the time.</p>
