Hello Jiri Vanek,
It make sense that ITW won't support IE since applets are completely dead.

Thanks very much for your quick reply.

I'm afraid my answer will make you really unhappy.
ITW supports on windows *only* javaws. The pure plugin for internet explorer is not even far close
to the javaws.
There is unofficial port of ITW to windows, but it is still bound to NPAPI. That means, that it runs
everywhere **except** IE.

So to make ITW works in IE you need to write plugin from scratch.

I'm sorry for bad news, but - applets are dead. I mean seriously and completely dead. All browsers
have cut those APIs away. Java have removed any traces of applet support too.
To run legacy stuff for fun, ITW allows you to run javaws -html some_url  which will parse applet
from html page, and lunch it in regular sandbox. But world fun is important. Without browsers
applets lost it spell. So fun, no serious work.
