Thank you - great webinar!

I have a question: If I want to integrate more than one different vaadin view in my jsp-pages, i.e.

    <vaadin:ui url="/example1"/>
    <hr>
    <vaadin:ui url="/example2"/>

must I implement a separte subclass of com.vaadin.ui.UI for each?

If yes, how would the web.xml (init-params, servlet-mappings) look like?

Best regards,
Roland

You need to define two different servlets and they can use the same UI implementation if you want. Map them to the “example1” and “example2” URLs and it should work.

Thank you for your answer!

One more question:
Which one of the two servlets should map to the url-pattern " /VAADIN/* " ? Both is not possible.

/VAADIN is used to serve static resources, so you can pick any of them.
