How to use a session, created in a jsp page, in a php page

Question

Hello, forgive me for the newbie question.
Here is my problem:
I want to have a jsp page create a session, set some session variables and then redirect to a php page which will access those same session variables.
I have the redirection worked out, but I can't seem to find out how to use the jsp session in my php script.
Is this possible at all, and if so, how does it work?

Note that javascript runs on the client side, and JSP runs on the server. JSP and the session objects are NOT available to javascript in reaction to the user.
If this function is called only when the page is first created, not when the user interacts with the page, or if you want that value to be constant with respect to the javascript, then you can do this:
<%
  String someValue = (String)session.getAttribute("theAttributeName");
%>
<script type="text/javascript">
     Calendar.setup({inputField:"f_date_dfFirstPmtDate",
                                          button:"f_trigger_dfFirstPmtDate",
                                         singleClick:true,
                                          ifFormat:<%=someVale%>});
</script>
