Guice

I have a Google Appengine/Guice/Wicket Application. My problem is that due to the mapping I can't access the /_ah/admin Page anymore. My Servlet Module says: serve( "/*" ).with( WicketServlet.class, getWicketServletParams() ); so far it is more or less expected that accessing /_ah/admin gives a 404. I problem is that I don't find a workaround. I tried different combinations of serveRegex(), but even serveRegex( "/.*" ).with( WicketServlet.class, getWicketServletParams() ); leads to problems, as the URL dispatching of Wicket gets broken. The application keeps on repeating the Path (e.g. /list

I was reading the Guice documentation, and came across a section labeled Eliminate the Cycle (Recommended) which peaked my interest because it's exactly the issue that led me to the documentation today. Basically, to eliminate cyclic dependencies, you "extract the Dependency Case into a separate class." Okay, nothing new there. So, in the example, we have. public class Store { private final Boss boss; private final CustomerLine line; //... @Inject public Store(Boss boss, CustomerLine line) { this.boss = boss; this.line = line; //... } public void incomingCustomer(Customer customer) { line.add

Do I need to create a new module with the Interface bound to a different implementation? Chef newChef = Guice.createInjector(Stage.DEVELOPMENT, new Module() { @Override public void configure(Binder binder) { binder.bind(FortuneService.class).to(FortuneServiceImpl.class); } }).getInstance(Chef.class); Chef newChef2 = Guice.createInjector(Stage.DEVELOPMENT, new Module() { @Override public void configure(Binder binder) { binder.bind(FortuneService.class).to(FortuneServiceImpl2.class); } }).getInstance(Chef.class); I cannot touch the Chef Class nor the Interfaces. I am just a client binding to

How do you initialize this: class A { final B b; A(B b) { this.b = b; } } class B { final A a; B(A a) { this.a = a; } } DI framework, reflection, better design? Motivation and a use case (added) : My particular use case is simplifying field access in A 's and B 's sub-classes. So I'm injecting them to shortly reference them by fields in the derived classes without a need to declare explicitly in each sub-class. There is also a recommendation on DI that objects should better be immutable: Guice best practices and anti-patterns . You could use a factory method class A { final B b; A(B b) { this

I'm getting null pointer exception on the field injection of a server which is started as an akka actor. Schedular part: private ActorRef myActor = Akka.system().actorOf( new Props(Retreiver.class)); @Override public void onStart(Application app) { log.info("Starting schedular.....!"); Akka.system() .scheduler() .schedule(Duration.create(0, TimeUnit.MILLISECONDS), Duration.create(30, TimeUnit.MINUTES), myActor, "tick", Akka.system().dispatcher()); } Retreiver class part: public class Retreiver extends UntypedActor { private Logger.ALogger log = Logger.of(Retreiver .class); @Inject private

I have a Swing application that I would like to convert from spaghetti to using dependency injection with Guice. Using Guice to provide services like configuration and task queues is going great but I'm now starting on the GUI of the app and am unsure of how to proceed. The application is basically a JFrame with a bunch of tabs in a JTabbedPane . Each of the tabs is a separate JPanel subclass that lays out the various components and needs services to perform actions when certain buttons are pressed. In the current application, this looks somewhat like this: @Inject public MainFrame(SomeService

I would like to integrate CXF with Google Guice. I am already using Guice in my project and I want to avoid adding extra dependencies. CXF was my choice because one of the requirements is to be able to provide XML, JSON, JSONP and SOAP interface to the users of the services without having duplicate code (right now we have SOAP-specific classes, for XML we use Struts and for JSON we wrote our own parsers, I know, I feel dirty too). Anyway, afaik , CXF can fulfill this requirement, so it seems I'm stuck with CXF. Any ideas or pointers or advice on how to integrate Guice with CXF? I thought of
