Embedded browser control does not display

Basically I embedded a browser into my application. However the request I want to view (google) does not show in the application despite my code linking to it. Any ideas?

BrowserFieldConfig myBrowserFieldConfig = new BrowserFieldConfi开发者_StackOverflow中文版g();
         myBrowserFieldConfig.setProperty(BrowserFieldConfig.NAVIGATION_MODE,BrowserFieldConfig.NAVIGATION_MODE_POINTER);
         BrowserField browserSession = new BrowserField(myBrowserFieldConfig);
                     //browserSession.
         browserSession.requestContent( "http://www.google.com" );
         add(browserSession);**

It need MDS service to be running. Check for MDS. it will work.
