Use File > Import > Existing Project into Workspace to add a sample project to your workspace.

Important: the EGL RUI Technical Sample, EGL Dojo Sample, and Mortgage Calculator require the widget projects (org.eclipse.edt.rui.dojo_0.8.1 and org.eclipse.edt.rui.widgets_0.8.1). If you do not already have them in your workspace, create a new EGL project (File > New > EGL > EGL Project) and pick one of the Web 2.0 client application templates. The EGL Dojo Mobile Sample requires the projects for mobile widgets (org.eclipse.edt.rui.dojo.mobile.widgets_0.8.1 and org.eclipse.edt.rui.widgets_0.8.1). If you do not already have them in your workspace, create a new EGL project and pick one of the Mobile Web client application templates.
