BookExampleBundle

How can I solve this? My goal is to run it on server.

I just take this source from here: Link and paste it on eclipse.

You need the book example classes in your classpath. You might want to step back a little and learn more about how to run Java web apps before trying all this. You're trying to import a class, and that class needs to be available somehow to the container, e.g. in a jar file in the WEB-INF/lib dir.

It looks like you're using Eclipse. There are probably examples and tutorials on the Eclipse site about how to create web apps and include 3rd party libraries. Then you can ask where the book example code lives (or maybe it's right on the Vaadin web site) and include that in your web app.
