Go to http://www.ies.co.jp/math/java/conics/draw_parabola/draw_parabola.html

scroll down to "APPLET" and you should see the applet.
In IE 6.0 it opens. In k-meleon 1.5.3 it says "after installing the plug-in click here".

I have everything in "Tools > Privacy" unchecked.

In F2 > javascript, only "Enable JavaScript" is checked.

"about;plugins" shows:

1.) IMHO Your installed plugins do not include the needed plugin.


Note: Two technologies have been called Java.

"Java Script" is a script programming language that is executed by the browser.

And then there is "Java" that is a programming language that is executed by the JVM (Java Virtual Machine) by Sun/Oracle. So in some cases the browser needs the Java plugin of the JVM. Java Applets in the Internet always need by the later.

BTW I have created some of the best Java Lake Applet pages in the Internet. This home page has been created and tested with the help of the K-Meleon browser. There You even find a sub page that was made to test whether K-Meleon can execute a Java Applet if the JVM originally developed by Sun is installed. smiling smiley


2.)My K-Meleon and system setup: I set the about:config value of my K-Meleon for the value of plugin.expose_full_path to true

I have installed the needed Java (JVM) runtime.

My about: plugins shows Java(TM) Platform SE 6 U30

File name: D:\Programme\Java\jre6\bin\new_plugin\npjp2.dll
Next Generation Java Plug-in 1.6.0_30 for Mozilla browsers

I can render/operate the applet at "Go to http://www.ies.co.jp/math/java/conics/draw_parabola/draw_parabola.html"




3.)Problem Solution:


Go to http://www.oracle.com/technetwork/java/javase/downloads/index.html and

download and install a current JVM version or version 6 update 30 or 31 like me.

Sidenote: If You are on an older Windows system prior to Windows XP SP3 You may need to search for an older Java engine (JVM version? maybe even 1.3.x) because the current will not install any more. Oracle used to have older installer files at another location. But I have not searched lately.

Complication for all K-Meleons including and prior to version 1.5.4.


The file D:\Program Files\Java\jre6\bin\new_plugin\npjp2.dll does not work and raises an exception that tells You upgrade to the new Firefox (at least version 3.5.x).

This is a Oracle Java Bug and it can be resolved by using either K-Meleon 1.6 or by copying npoji610.dll

from .\programm files\Java\jre6\bin\npoji610.dll

to .\programm files\K-Meleon Install directory\plugins\npoji610.dll

Reason why this works: the plugin that works for K-Meleon 1.5.x and some other browsers gets precedence to the buggy new plugin if it is in K-Meleon's own plugins folder.

Note: All plugins in K-Meleon's own plugin folder get prefered over any other plugins installed somewhere else on Your system even if these can render the same MIMEtype. This fact can be used to influence which plugin is used.

Lets hope this info helps You.

Thanks for the help!
I will try that.
