Hi, I have an app using Restlet in Google App Engine. I have warmup requests enabled to theoretically do some heavy data loading before the first real user request but it does not appear to work. The first real request does all the loading which is not ideal!
http://code.google.com/appengine/docs/java/config/appconfig.html#Warmup_Requests An example web.xml and Example.java class are shown below. I was expecting when I set load-on-startup=1 in web.xml that Restlet would initialise all the routes and call my init() method during the warmup request but this does not appear to happen. Ideally, I want my data loaded and as much of Restlet initialised during the warmup request from App Engine. I have read that I could create my own "warmup" servlet to load the data but this does not load Restlet in any way but it would allow me to load my data from the Datastore. Can anyone point me in the right direction? Cheers, John ***** extract from web.xml: ***** <servlet> <servlet-name>ExampleServlet</servlet-name> <servlet-class>org.restlet.ext.servlet.ServerServlet</servlet-class> <load-on-startup>1</load-on-startup> <init-param> <param-name>org.restlet.application</param-name> <param-value>my.app.Example</param-value> </init-param> </servlet> ***** Example.java: ***** public class Example extends Application { public Example() { getStatusService().setEnabled(false); // this is needed to prevent Restlet displaying its own custom error pages } /** * Initialise the app * @param context */ private void init(Context context) { // // I do my heavy data loading from this method // } /** * Creates a root Restlet that will receive all incoming calls and route the * requests to the appropriate resource handlers. This also attaches different * authenticators depending on the resource being requested. * */ @Override public Restlet createInboundRoot() { Context context = getContext(); init(context); // call init to load the data before we handle the request // NORMAL: user licence auth and routing Router userRouter = new Router(context); // ..... user routes // check the licence key for each request LicenceAuthenticator licenceAuth = new LicenceAuthenticator(context, licences); licenceAuth.setNext(userRouter); // ADMIN: needs special auth Router adminRouter = new Router(context); // ..... admin routes // authenticate the admin AdminAuthenticator adminAuth = new AdminAuthenticator(context); adminAuth.setNext(adminRouter); // Create routes for regular and admin users that go through the authenticators Router rootRouter = new Router(context); rootRouter.attach("/detect", licenceAuth); rootRouter.attach("/admin", adminAuth); return rootRouter; } } ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2933568
