I tried to create a very easy Roo Sample Project (the one you find on roo homepage: http://www.springsource.org/spring-roo). It uses GWT and Hypersonic in memory DB.
When i try to use mvn gwt:run everything is ok, but if I use mvn tomcat:run to start tomcat then in my browser I can only see a page with "loading..." in it and nothing happens.
It seems there are no error in tomcat startup.
Am I missing something?
No, you are not missing anything. You cannot use the same Maven goal when you are running a GWT application with Spring MVC.
Depending on your view controllers pick one of the below.
GWT : mvn gwt:run
Spring MVC : mvn tomcat:run
