Question

I use to pass data between *.java and *.jsp, since this is a MVC framework, it will go by the *.java first. so i used request.getSession().setAttribute("test", "01010101010") to save the value, and then in *.jsp, use request.getSession().getAttribute("test") to get value.
But it returns a strange string "682342348" all the time.

Answer 1

This might be a javascript question now, try adding quotes around the value of the alert parameter.

Change this:

<script>alert(<%=request.getAttribute("test")%>);</script>

To this:

<script>alert('<%=request.getAttribute("test")%>');</script>
