Applet and PHP

flasher44

I don't know how to load a class file using this HTML code using PHP :

<APPLET title="test" height=140 
      alt="test" width=420 code=CASapplet.class></APPLET>

I tried this simple PHP translation but the applet refuse to load and I have a red cross instead of the applet...

<?php
echo "<BODY><HTML>\n";
echo "\n";
echo "\n&quo
D78
t;;
echo "    <APPLET title=\"test\" height=140 \n";
echo "
D4A
      alt=\"test\" width=420 code=CASapplet.class></APPLET> \n";

Could somebody help me ?

kumschick

this is the right way...! 😃

<?php

echo"
<APPLET title=\"test\" height=\"140\" alt=\"test\" width=\"420\" code=\"CASapplet.class\"></APPLET>
";

?>

Unfortunatly, it does not work, the applet still does not load...

There should be a trick, I don't understand, how to load the applet, to be executed on the user browser, because it can't be executed on the web server as php does.

kumschick

is the path right?
are you sure that the class is in the same folder than the php page? where did you get this class?

try to start the class with normal HTML to be sure that the you didn't forget something.

Shit, you're right even if I call an html file it does not work, I don't know where to add the path, because this file when opened by my browser works but as soon as I open it through my web server it does not anymore.

kumschick

put the file in the same folder as the html or php page.

flasher44

I did it, but the file refuses to load.

I have some bad news for you Nearly all of your major browsers have stopped fully supporting Java applets. It's not your code that's the problem, nor your webserver; it's the fact that Sun Microsystems has been pulling away from AWT and Swing applets in favor of J2EE solutions with Java, so as a result, most browsers out there don't fully support them.

Your browser may now take up to 5 minutes to load a page with an applet (try it sometime and see what happens), or, it does not load an applet at all.

OK, but why then when I open the file on my PC, the HTML page works and the applets all load without problems ???

I don't understand why it work in local and not through a web server. Do I need to set up a java server on my webserver ?

ppowell

if the applet is local to your PC machine and your machine acts as a server, check to see if the webserver itself has the ability to load via JRE. Use appletviewer if you have it to see if the applet is viewable or not before you go further.

In all actuality this is not a PHP issue and you might want to take this to a Java forum instead to ensure you're getting the right help, unless you do find some Java gurus here willing to help.

I'm using easy-php 1.7 to test it, but maybe you just have to test the applet yourself, you can download it here.

And test how to get it working.

Thanks for your help.

kumschick

here it doesn't work!
but maybe because i' using Microsoft Virtual Java Machine and not Sun Java.

even on local it doesn't work!

so it think it's because of the MS VJM.
Maybe I have to install Sun Java for it, but it don't want to just to test the script.

sorry

désolé
😉

So nobody here knows how to use such applet on a web server ?

There is no problem with client-side Java and PHP.

PHP does not know, or care about, your applet. It simply generates the text you tell it to generate.

If you generate a valid HTML applet tag pointing to a valid location where a valid classfile can be retrieved, your browser should fetch and execute the applet, unless Java is broken in your browser. Either way, it has nothing to do with PHP. The browser fetches the applet separately and PHP is not involved in that process.

If the applet isn't loading, it's either because you are not generating a valid HTML applet tag that embeds a valid applet call, or because your classfile itself is corrupted.

<applet codebase="http://java.sun.com/applets/jdk/1.1/demo/NervousText"
code="NervousText.class" width=400 height=75>
<param name="text" value="How to embed an applet">
This text will appear for browsers with Java disabled.
</applet>

is the same as

<?
echo "
<applet codebase=\"http://java.sun.com/applets/jdk/1.1/demo/NervousText\"
     code=\"NervousText.class\" width=400 height=75>
   <param name=\"text\" value=\"How to embed an applet\">
   This text will appear for browsers with Java disabled.
</applet>
";
?>

Simply follow the rules for embedding text in PHP double-quoted strings.

Thank you !! But could you confirm that the web server used does not need to have a java server installed to used an applet on my site ? Because when I try to use the "NervousText.class" localy it does not load either...

Java applets are run entirely within the client (ordinarily a web browser) and the only involvement of the web server is HTTP delivery.

The web server should be configured to deliver .class files as type "application/octet-stream." That is the default configuration for Apache.
