Creating Secure Vaadin Applications using JEE6 - without JSPs?

Hi,

I read this article: https://vaadin.com/wiki/-/wiki/Main/Creating%20Secure%20Vaadin%20Applications%20using%20JEE6
but I was wondering if the same could be done without using JSPs. So, I’d like to do everything the same as in the example but instead of creating 3 JSPs, I’d like to just use pure Vaadin. Any ideas? Is there an add-on that would help me do this?

Thanks…
