Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

$_SESSION is one of the superglobal arrays in PHP, and you need square brackets to access the elements of an array (unless, of course, you've declared a function called Session). To output a value to the page, you need to echo it, and it will need a semicolon at the end of the statement.
Hmm... You said the page was completely blank, no source code? I've got an idea that that sort of problem may be caused by server timeouts (trying to remember something I was reading a couple of weeks back). I've had a go myself (on Apache running on Localhost) and am not getting any errors for missing parameter/wrong class name (or even uncomiled Java Source code), but I am still getting a grey box on't page.
Have you had a look at the web server logs, to see if there are any revealing error messages? For the missing class file, I have this in access.log:
Hi, and thanks (I keep saying that - this forum really helps me), ok, here's the scoop so far.
I looked in the log '/var/log/httpd/error_log) and found I had a syntax error in my PHP code, so, the PHP engine "eeeps" out and shows a blank 'stare'...
I corrected that and did get a grey (failed) applet - but that seems to be due to the fact that I did'nt set the Session Var yet. The log mentions something like "Undefined Index" - so that's already a big Quantum Leap ahead 4 me!
Life would be easier if I had some sort of console, especially @ client-side, so I could "vent" messages using the System.out.println() directive...the jconsole is cool enough, but it shows statistics only - unless I've missed the clue here
Ok, so far, I know where to "tickle" the ol' girl... :-)
