The caramba framework is built from bottom to top with one main goal: creating Responsive, Rich Internet Applications.
With the AJAX technology we could already achieve this, but it was hard to debug, error prone and time intensive to make it work.
We are sure that simplicity can be achieved by following the event driven architecture: Caramba is 100% event driven, so very, very easy to use.
You don't need to learn another language. Just the good old java syntax and JSP, that's all you need to know to get started.
