applets works only offline.
May 31st, 2009, 4:15pm  
Hi,
I've made a simple demo application for CaptureMJPEG lib, once exported as applet I've signed all the jars with my key.

Now if opened offline works correctly, but online didn't starts (freeze after asking about trust).

Can sameone help me?

EDIT: I can't post links, if interested ask me via PM


Tnx a lot

When you have a problem with an applet, look at the console.
For your, it says:
Quote:
Exception in thread "Animation Thread" java.lang.NoClassDefFoundError: IllegalName: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"

Looks like you have mixed up something.

Or, rather, as I saw after downloading public_demo.jar at the same location as your first page, the Wiki is confused: instead of the jar, it serves an HTML error page:
Quote:

Tnx a lot.

I've uploaded all on http://capturemjpeg.lilik.it/applet/axis_demo.html ad it works  Cheesy Grin

On another hosts I've found this strange behavior.
Any idea?

$ firefox http://capturemjpeg.lilik.it/applet/public_demo.html
