vaadin + osgi + addon(InvientCharts)

[Peter]

Hey Guys,

I'm quite new to Vaadin and I'm not a master in OSGI aswell,but I got
it running for my Application and liked it very much.
Now I want to extend my UI with the InvientCharts addon provided at
the addons section at the Vaadin page.

Well, I followed the Instructions served from this page:
http://redvoodo.wordpress.com/howto/howto-use-vaadin-add-ons/

So far so good, my problem starts with that InvientCharts needs an
ApplicationServlet which injects the references to the javascript
libraries into the html body. But I didn't find a way to do so within
the osgi environment.(I tested this addon in an usual JavaEE
environment,it's working)

So I kindly ask you for some hints on how to inject these references
to the javascript libraries into my output html file, which will
pretty sure solve my problem. (Is there any way to do this within my
init()-method?)

p.s. I used Kai Toedters Demo to get my Vaddin+Osgi working and so I'm
using DS.
Thanks to him for this demo and thanks in advance to any readers.

Peter
