Tomcat 7 with Vaadin, Hibernate, Eclipse and Maven 3

I'm trying to integrate maven in my existing Vaadin project. There is several errors and weird things. First of all I can't understand what I should do to make tomcat instance used by maven is visible in eclipse. I mean that when I run tomcat7:run, Tomcat instance, preconfigured in eclipse, stays stoped. Also I can't understand which Tomcat instance maven uses and why it creates Tomcat configuration files in project folder, because when I'm trying to open application in browser after tomcat7:run I recieve error 404.
By the way there are several questions about compilation of Vaadin widgets. I configured vaadin maven plugin and gwt maven plugin. When I'm running mvn gwt:compile it seems that everything is ok, but when I'm trying to compile Vaadin widgets using eclipse plugin I have the following error

Otherwise, if I compile widgets using mvn gwt:compile and after that build war using maven and deploy it I recieve en empty page in browser.

Also when I'm trying to run application as run on server I have the following exception
