Appliction.application().servletConnectURL();

Otherwise, if you might use the userInfo dictionary upon dispatching  
the request so you can access it anywhere you've got access to the  
WORequest object. e.g.,
this.context().request().userInfo().valueForKey(Application.APP_URL);

public class Application extends WOApplication {
	private static final Pattern MAIN_URL_PTN = Pattern.compile("^(.*\ 
\.woa)(?:/wa/DirectAction/default.*)$");
	public static final String APP_URL = "appUrl";
	...
	public WOResponse dispatchRequest(WORequest aRequest) {
		WOContext aContext;
		String url;
		Matcher m;

		aContext = new WOContext(aRequest);
		url = aContext.completeURLWithRequestHandlerKey 
(directActionRequestHandlerKey(), "DirectAction/default", "", false, 0);
		m = MAIN_URL_PTN.matcher(url);
		if (m.matches()) {
			aRequest.setUserInfo(new NSDictionary(m.group(1), APP_URL));
		}
		return super.dispatchRequest(aRequest);
	}
}

The front door, so to speak, is dependant on the desired domain of  
deployment. If you're using virtual hosts (which is often the case)  
it's not as simple as detecting the host name of the server running  
the app. So specifying the adaptor url desired for the app is the way  
to go and/or querying the incoming request object...
