问题 I have a standalone application with embedded Jetty and Wicket. I'd like to use CDI for injection. So I've found http://docs.jboss.org/weld/reference/latest/en-US/html/environments.html#d0e5286 and now I'm trying to add this programatically, but it's quite complex. How do I code that? Other sources I've found are: http://osdir.com/ml/java.jetty.support/2007-02/msg00198.html http://docs.codehaus.org/display/JETTY/JNDI So far I have: Server server = new Server( 8080 ); Context ctx = new Context

问题 I want to write a simple Java Desktop Application using Java Swing. Usually I use Spring Framework to do the dependency injection and build the whole class structure. However, I've seen that CDI is becoming more and more popular and want to give it a try. I would like to do the Dependency Injection of my project using CDI, but I don't know if this is possible without a Servlet container (as it is using Spring). Every single tutorial seems to be related with servlet containers or application

问题 Using Glassfish 3.0.1 ... If I have a web application accessing EJBs in another application remotely, and the remote application containing the EJBs is redeployed, I get a javax.ejb.NoSuchEJBException (see stacktrace below). Shouldn't this work? I can see that the EJB in question was successfully deployed, using the exact same JNDI name. Is there any other way to fix this than to restart the web application? It should be noted that in this particular example that the stacktrace is from, I'm

问题 Say I have a web service / a REST resource that is called with some HTTP header parameters. The resource method builds a complex data object (currently a POJO) and eventually returns it to the client (via Gson as JSON, but that doesn't matter). So I have this call hierarchy: @Path(foo) ProjectResource @GET getProject() -> new Project() -> new List<Participant> which contains lots of new Participant()s -> new Affiliation() If I want the Affiliation object to be e.g. populated in English or

问题 I have a few classes that observe some CDI event. Is it possible to declare which class should be used in different cases? For example I have class that produce events: class Producer { @Inject private Event<SomeEvent> event; public void fire() { event.fire(new SomeEvent()); } } And I have two consumer classes: class ConsumerA { public void onEvent(@Observes SomeEvent event); } class ConsumerB { public void onEvent(@Observes SomeEvent event); } How can I use ConsumerA instances in one case

问题 Please note: This question is about CDI scopes as we are using CDI scopes in the app and not JSF scopes. 1) Controller Bean (TestController.java) which is in RequestScoped (enterprise context) is called index_cut.xhtml, when we come for first time on this page. 2) On button “Load”, we load the following method to populate the sapFinancialPeriodList which works fine and displays the data 3) After changing the content on the page and submitting, the sapFinancialPeriodList appears as NULL in the
