Subject Re: My problem: I cannot successfully get or set a session attribute from a JSP file.
Date Mon, 08 Dec 2014 21:31:03 GMT

Please make note that I do not see errors in the brower window, but in 
the brower console window.
If I have time later, I will create an error in my 's.jsp' server code 
and verify that an error is
reported in the console.
