How to use Barracuda?

Hi,

I am trying to make use of Barracuda Component model in a prototyping
exercise to get a Feel of 
Barracuda Presentation framework and hence recommend this framework for
further projects.

I would be using custom developed Event Model to trap the events and process
them in my business logic.

My question:
I have a HTML page with TextFields, TextAreas, DropDrowns (Comboboxes),
Buttons.

Now in case of JSP, I would have embedded the Java Code (to populate these
components) within 
the HTML page and renamed the pageas .JSP.

Incase of Barracuda, how do I achieve this.  Also, where to create the
JavaScript?

Cheers & All:-)s
