Dave, make sure you have published your application to the server
correctly.
Copy the contents of this folder: .....\workspace\GWT Test Project
1\war
To your webapps folder: ....\webapps\gwt_test_project_1
"webapps/gwt_test_project" should look like this:
gwt_test_project
WEB-INF
GWT_Test_Project_1.css
GWT_Test_Project_1.html
Good luck!
