Running Applets under Microsoft Windows Systems is not a problem.
Just follow this link to install last version of Java Web Start.

Mac OS X

On Mac OS X, Java applets work best in Safari, which takes advantage of the latest version of the standard Java Internet Plug-In.
Mozilla Mac OS X users need to install a standalone plugin to running swing applets (Java 1.4).
Just follow the instructions on the plugin download page.
Internet Explorer users under Mac OS X will find probably this error:
Slider no class found
This append because the browser try to use a older java version that doesn't support swing (1.3)
If you have a Mac why do you use Microsoft Internet Explorer?


Under linux probably you have to configure manualy your browser to the java plugin:

- Mozilla and Firefox

On Linux, Mozilla requires JRE 1.4.2 or later.

Mozilla 1.4 and later, and Mozilla Firefox, are compiled with gcc 3.x. A gcc 3.x compatible version of the Java plugin must be used. JRE 1.4.2 and later contain a compatible plugin.

If you installed the JRE 5.0 RPM, this plugin is /usr/java/j2re1.5.0/plugin/i386/ns7/libjavaplugin_oji.so - and to install it for Mozilla (including Mozilla Firefox), do the following:

If you install your JRE in a different way (self extracting package, debian package, etc), libjavaplugin_oji.so will quite likely be in a different location. Do not just blindly use the command listed above!

In JRE 1.4.2, this file was in plugin/i386/ns610-gcc32

Always make a symbolic link, as shown above, instead of copying the plugin.
If you copy the plugin, your browser will crash every time you open a page containing a Java applet. You have been warned!

If you are using an older Linux distribution, you may need to install the gcc3 support libraries, as the gcc 3.2 version of the Java plugin requires libgcc_s.so.1 to operate.
You may be able to find packages using Google.
If you are using an old or unofficial build of Mozilla (1.4a or later) or Mozilla Firefox, you can check which compiler was used by entering about:
buildconfig in the location bar and pressing enter.
You will see a line such as "gcc version 3.3.2", which will show the compiler that was used.
If gcc2.9x was used, you need to use the ns7-gcc29 or ns610 plugin, not the ns7 or ns610-gcc32 plugin.
If you are using an older Linux distribution, you may need to install the gcc3 support libraries, as the gcc 3.2 version of the Java plugin requires libgcc_s.so.1 to operate.

Mozilla, Java plug-in and Debian

Currently it is not possible to use a free Java Virtual Machine as a Mozilla plugin because most of the free JVMs do not yet support the Java AWT (Java GUIs). So the non-free alternatives from Sun, IBM, or Blackdown are required. This is unfortunate as it means that your system becomes dependent on software that you are unable to validate and view yourself, relying on very few others to provide trustworthy code.

Nonetheless, to get the Java plugin running with an installation of j2sdk1.4.2_03 (from Sun and installed as described in Section 48.1) for Mozilla 1.5, link the appropriate library to the mozilla plugin directory:

# cd /usr/lib/mozilla/plugins
# ln -s /usr/local/bin/j2sdk1.4.2_03/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so

Then run Mozilla and visit about:plugins to ensure the plug in is found.
