I tryed to put a book on a webpage using java DjVu applet.
The project is made with an index-file and separate .djvu files - each around 200kb
Responsetime is really slow compared to djvu-plugins.
I'm using javadjvu0-8-09, which should be the latest version afaik.
My page can be seen here: http://magleby.sommerdal.com
You might need more information - just ask
