Answer 1

Try including the JAR via Project Structure settings ( tab Libraries ). If that doesn't help you try checking this step by step guide how to set up Vaadin with IDEA:

1) Download the Vaadin JAR

2) If not already done, install a Tomcat server

3) Start IntelliJ and create new project from scratch ( all steps below are performed with IntelliJ 9 )

4) Type of project is Java Module and as desired technology you select Web Application. This will create the web folder, including the WEB-INF dir and a web.xml file

5) Create a web/WEB-INF/lib folder and place the Vaadin JAR into that folder

6) Goto Project Structure | Modules and let your module depend on the Vaadin JAR. Mark it as export

7) Create a HelloWorld class and adjust your web.xml file, as described in the book of Vaadin

8) To run/debug, create a new "Tomcat Server" configuration. If not yet present, configure a Tomcat server by providing the link to the installation dir of your Tomcat server
