I saw 
http://gwt-openlayers.hg.sourceforge.net/hgweb/gwt-openlayers/gwt-openlayers/file/c26877cf76a4/showcase/src/org/gwtopenmaps/demo/openlayers/client/examples/vector/BasicWFS.java

and wrote this code:

		mapWidget.getMap().addControl(new PanZoomBar());
		mapWidget.getMap().addControl(new LayerSwitcher());
		mapWidget.getMap().setCenter(new LonLat(146.7, -41.8), 6);

		// eventually add the map widget to div:map
		DockPanel dockPanel = new DockPanel();
		dockPanel.add(mapWidget, DockPanel.CENTER);
		dockPanel.setBorderWidth(1);
		RootPanel.get().add(dockPanel);

	}
}


But I don't see tasmania_roads layer.. Why?
