I'm not sure if this is all there is to the problem but if you're running your application on Tomcat you do not need to run code on the GWT code server. I can see in your address bar that you're URL has ?gwt.codesvr=127.0.0.1:9997in it. Try removing that.
EDIT:
In Eclipse you run the app with
http://127.0.0.1:8888/Project1.html?gwt.codesvr=127.0.0.1:9997
where Project1.html is the page you want to load.
In Tomcat the URL should be
localhost:8080/project
Where project is the name of the WAR file that you put in the webapps directory.
What ended up being the answer:
Don't forget that your libraries have to be in war/WEB-INF/lib. Where war is the top level folder that you put in Tomcat's webapps folder.
