I am new to Vaadin.
I have created template for my web application in HTML and JS.
How to use the developed template with Vaadin as am not sure if I will be able to develop same template using Vaadin only?
It may be possible to re-use some of the layout of the template using the CustomLayout layout component in Vaadin.
You can also render the contents of a template into a Label component, and display the label in the application. See http://demo.vaadin.com/sampler#LabelRich for a small demo.
Generally, though, the idea of templates and "pages" is orthogonal to developing applications in Vaadin.
