Guice

I'm trying to inject an ArrayList of String s with the help of Guice. I want to show a panel with many RadioButtons (for example) where an user can select some services to activate. Once selected, I would like to get all the names of the selected services and add them into a list, and inject this list to the manager responsible to create the services. Here is an example: public class UIProviderModule extends ProviderServiceModule { private ArrayList<String> requestedServices; public UIProviderModule(ArrayList<String> requestedServices) { this.requestedServices = requestedServices; } @Override

Background My understanding of Java generics is it being completely a compile time feature (mainly focusing on type safety checks). The type information for any generic class is lost at runtime ( type erasure ). Still, i see many frameworks seem to leverage the type information at runtime as well. For example, google guice Providers . The guice provider can instantiate and provide new instances of it's generic type at runtime. class Container { @Inject public Container(Provider<Content> contentProvider) { //This works at Runtime... but How ??? //When type's are not even preserved at runtime,

I'm using Jersey-Guice to configure a Jersey app, following this template . Everything works fine if the Injector returned by the GuiceServletContextListener.getInjector() method is created by Guice.createInjector() . If that injector is instead the child of another injector, then the bound resources (e.g., MyResource in the code below) are never added to the Jersey ResourceConfig and Jersey crashes with a complaint about missing root resources. I don't think the bound resources are even scanned, because the usual "INFO: Registering my.example.MyResource as a root resource class" doesn't

How can I use non-jersey resources with jersey resources with guice ? I want "/" to be handled by a plain servlet. But I want "/users" handled by jersey. Say I have a jersey resource with @Path("/users"). Using the following bindings will not work, it tries to map the "/" request using jersey which of course is not a jersey resource and I get 404. protected void configureServlets() { serve("/").with(LoginServlet.class); serve("/*").with(GuiceContainer.class, params); } All of the examples of jersey / guice I can find do something like serve("/rest/*".with(GuiceContainer.class, params); which

I'm trying to use Guice and make all the bindings with the help of an XML file. In my module (let's say "CustomModule"), I would like to load an XML file and parse it to set all the bindings. I'm able to load the XML file and retrieve all the values needed (below is an exemple of my XML file), but I'm unable to use those values to bind(interfaceValue).to(implementationValue); . What I've tried so far: Load the XML file, retrieve all the values and use them as : bind(Class.fromName(Ivalue)).to(Class.fromName(Value)); where Ivalue is InterfaceFoo and Value is Foo . Load the XML file as a

Suppose I have 5 classes A, B, C, D, E that all implement a common interface X. Each of the classes B, C, D and E has a field of type X (so they can be seen as wrapper classes). Which instances are created is determined at runtime, so I could have for example one of the following object graphs: E -> D -> C -> B -> A D -> B -> A E -> A A (The order is fixed and the innermost instance is always of type A, but otherwise there are no restrictions.) No I'd like to create this objects with Guice to avoid providing all their other dependencies by hand. What's the easiest way to do this? Currently it

This is a webapp running on Tomcat, using Guice. According to the docs we should be able to call ResourceBundle.clearCache(); to clear the ResourceBundle cache and presumably get the latest from the bundle property files. We have also tried the following: Class klass = ResourceBundle.getBundle("my.bundle").getClass().getSuperclass(); Field field = klass.getDeclaredField("cacheList"); field.setAccessible(true); ConcurrentHashMap cache = (ConcurrentHashMap) field.get(null); cache.clear(); // If i debug here I can see the cache is now empty! and ResourceBundle.clearCache(this.class.getClassLoader

First off, I'm using Google AppEngine and Guice, but I suspect my problem is not related to these. When the user connect to my (GWT) webapp, the URL is a direct html page. For example, in development mode, it is: http://127.0.0.1:8888/Puzzlebazar.html?gwt.codesvr=127.0.0.1:9997 . Now, I setup my web.xml in the following way: <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display
