title: Configure GWT in Eclipse
body: <p>Installed Google <code>App Engine 1.2.5</code> and <code>Web Toolkit 1.7.1</code>. However I still get a red underline whenever I import <code>gwt</code> and user any of it's classes like <code>graphCanvas</code>. How do I take this underline away? What haven't I configured correctly?</p>
