I don't like the folder "WebContent" so I call it "view" when creating a project and then the content of the generated .war is only:

1021 08-02-07 15:36 WEB-INF/classes/com/mydomain/projectname/session/Authenticator.class
0 08-02-07 15:36 WEB-INF/lib/
0 08-02-07 15:36 WEB-INF/classes/com/mydomain/projectname/session/
0 08-02-07 15:36 WEB-INF/classes/com/mydomain/projectname/
0 08-02-07 15:36 WEB-INF/classes/com/mydomain/
0 08-02-07 15:36 WEB-INF/classes/com/
0 08-02-07 15:36 WEB-INF/classes/
0 08-02-07 15:36 WEB-INF/

note: no web-content.

probably related to the packaging assumes WTP WAR default layout.
