问题 I'm trying to get CDI to work in my application, but I only get NullPointerExceptions when I do. When normally instantiating the playlistService, it works perfectly fine, but when I try to use CDI, it doesn't anymore. The server is able to start, but when I add beans.xml to META-INF/ and WEB-INF/ it's also not able to start anymore.

问题 For several days I'm trying to manage with JPA transactions after moving to WildFly 8 server and JEE7 and I cannot understand why in some cases @Transactional (javax.transaction.Transactional) annotation doesn't intercept method annotated with it. I cannot see any rule why sometimes it works and sometimes not.

问题 We migrated from Jboss EAP 5 to EAP 6 in our development environment. I now see the following in my JBOSS logs. I am trying to understand how this binding happens. I have read JBOSS docs on JNDI namespace binding. Still I am not totally clear how it works. Here is my log. java:global/customerCare/services/UserDaoImpl!com.example.services.UserDao java:app/services/UserDaoImpl!com.example.services.UserDao java:module/UserDaoImpl!com.services.UserDao java:global/customerCare/services/UserDaoImpl

问题 I'm working in a project deployed in Glassfish 4.1 . Dependency injection is made using CDI and I'm having an issue when trying to deploy the application. The error I'm getting is the following (usually I "translate" the name of my classes in the code so the whole post is in the same language, I`ll not do that now so I can copy/paste and avoid some translate typing mistakes): Server log org.glassfish.deployment.common.DeploymentException: CDI deployment failure:Exception List with 3

Is it a bug or Jee spec changed? Is there a way to globally fix it for entire application? Example classes: @ApplicationPath("/rest") public class RestConfig extends Application { } @Path("/test") public class TestResource { @GET @Produces(MediaType.APPLICATION_JSON) public TestEntity get() { return new TestEntity
