Using Add-On

Good morning together.

I am new beginner at Vaadin since I shall make a project for my studies under the use of Vaadin.
I need your help urgently.

Now I would like to draw circles and have download the “Canvas Widget” Add On of Vaadin.
I have the package unpacked and the Jar files slid into the corresponding folder

It is my problem lthat I don’t understand how i can use the Add-On. I don’t know where I can use the library.
An Example how i can insert an Add-On would help me very much.

It would be nice if somebody could help

Many thanks

Start by reading the chapter about using the addons in
The Book Of Vaadin
