Hmmm.  About all I can think of at the moment is to examine Tomcat with a
debugger and step through
org.apache.catalina.connector.Request.doGetSession().  Or you may want to go
back to org.apache.catalina.connector.CoyoteAdapter.postParseRequest().
Another thought is to run a TCP/IP trace and make sure the appropriate
cookie is being sent from the IFRAME.  The cookie name is JSESSIONID.

This should show you exactly what's happening with attempting to get the
session from the IFRAME.

1.  What version of tomcat are you on?

Tomcat 5.5

2.  Does the URL for the outermost window have "jsessionid" in it?
No, its uses standard cookies for persistence.  I did try 
appending jsessionid to my IFRAME src and several variations.

3.  What does the URL for the IFRAME look like?

I build the IFrame in a JSP for testing as follows:

<% String sessionid = request.getSession(false).getId();
      String url = "run?PJMR=" + mrId + "&id=" + appId + 
         url = response.encodeUrl(url);
      <iframe src="<%=url%>" >

It does call the servlet "run" correctly because I get a 
breakpoint fine.  The PJMR request parameter references a 
session based "Action" 
object.  As an alternative, I could enhance our server side 
framework to
  store these action objects in a static map instead of user 
sessions I suppose.

Thanks,  Paul
