Hi,

Ok, I hope there's an answer for this one...
I run a server (CentOS 5.2) with Java and PHP installed.

The code for the applet in the client page is:
(html excluded - I assume that this is ok...)

Where the top bit is a test and belongs in the ac4.html, the other (lower) one stands in ac4.php.

When I enter the full URL

the page shows a grey block - of a failed applet.

with

I only get a blank page, and no page source...

The title does'nt show either.

Is there an issue with permissions? I ran a test with a clock applet and that runs, so the server can "dish" out applets...

Please help...

Big tnx

Thor
(PS I could'nt decide where to put this cry for help - if the alternative was something else, then I apologise, of course)

Hi linusr,

Shouldn't that be:
?

$_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.

Arrays in PHP

Hope this helps,

No go...I still only get a blank page, I even changed the applet's parameters:

(floop.class does'nt even exist - should'nt I @ least get a classnotfountexception or the like?)

to force it to load a non-existing Class, but the same results manifest themselves. I even deleted the page, and there I do get a 404 page (notfound)

(slightly depressed sigh...)

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:

localhost - - [10/Apr/2009:23:28:09 +0100] "GET /flibble.class HTTP/1.1" 404 355 "-" "Java(tm) 2 SDK, Standard Edition v1.6.0_0 Java/1.6.0_0"

... and this in error.log:
[Fri Apr 10 23:28:09 2009] [error] [client 127.0.0.1] File does not exist: /var/www/htdocs/flibble.class

There was no error logged for the missing parameter.

I must admit, in my first post I jumped on the first thing I noticed, and assumed you were trying to access session variables via PHP. Yes, I know what assume makes .

Oh, and I should have asked, you asked about permissions - what are the permissions on the various files?

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... :-)

Tnx!!!

Thor
