Hey,

I just got me a little project running in Eclipse using the Processing core lib.
Also I read all tutorials for working with Processing in Eclipse.

Everything could be fine, but I am stuck with a problem.
I added a HTML file to my project, just wrote:

1. <applet code="TestProject" width="600" height="400"></applet>

and then tried to run the applet in firefox.
Unfortunately the applet is not loaded but fires an error message:

1. java.lang.NoClassDefFoundError: processing/core/PApplet

The applet runs properly when it gets started within Eclipse, but not when I try to implement it in my website.

Does anyone have an idea about that? Is there a different way to automatically generate a HTML file with an applet?
I really need help on this!

You can reply in English or German, too.

Thanks in advance.
