I am confused.. creating a new Vaadin project

I see - acual for a new Vaadin 7 project the xml.file isn’t necessary - annoations will do the job.

But if I create a new empty Vaadin 7 project with eclipse - text example code with EEpreview doesn’t work.

The context is Test - and the internal browser window shows the directory

Directory: /Test/
META-INF/ 0 bytes 06.09.2013 19:22:48
VAADIN/ 0 bytes 06.09.2013 19:15:44
WEB-INF/ 0 bytes 06.09.2013 19:22:48

What is going wrong? This problem is new for me - perhaps there is a context with my last Vaadin update to 7.1.4


P.S: The next weird problem - for existing project the jetty server ist now out of order - tomcat works fine:
com.vaadin.server.ServiceException: Could not read atmosphere settings
Reason: java.lang.ClassNotFoundException: org.eclipse.jetty.websocket.WebSocketFactory$Acceptor

I cleaned all dirs - problem still exists

Update: Now i cleaned every cache and started the ivy tool chain again - similar problem now:

Starting the preview server displays following message:
