I am reading through the Public Review Draft of the Web Beans specification (JSR-299) and I am wondering why it is so 'tightly coupled' to JSF? Especially the Conversation Context seems only be specified for JSF. I understand, that it is a goal of WebBeans to integrate JSF and EJB3. But would it not make sense to specify the concept of...
I know it is still not quite popular, since the spec was released just a few months ago. I haven't "installed" weld yet, I'm just reading, and by this question I want to make sure I've understood this important point correct: Is resolution of beans that are in 3rd-party jars achieved by declaring them as <alternatives> in your beans.xm...
In Spring it was possible to instantiate any class by defining the corresponding bean in xml conf. It was also possible to instantiate more then one bean for the same class with different parameters..... Are the such features in CDI as well, namely is it possible to create different instances of the same class with different initializ...
How can I use JSR-299 CDI to inject (not annotated) beans from external libraries? Examples: Interface X and its implementations come from a third party lib. How can I decide which implementation to use? class A { @Inject private X x; } What if I had several classes using the X interface but different implementations? cl...
I was reading a Wikipedia article about Java EE application servers here: http://en.wikipedia.org/wiki/Java_Platform,_Enterprise_Edition#Java_EE_5_certified It says that 2 APIs that Java App Services implement are: javax.enterprise.inject javax.enterprise.context These both relate to application context and dependency injection JSR-...
JSR-299 (CDI) introduces the (unfortunately named) concept of a resource: http://docs.jboss.org/weld/reference/1.0.0/en-US/html/resources.html#d0e4373 You can think of a resource in this nomenclature as a bridge between the Java EE 6 brand of dependency injection (@EJB, @Resource, @PersistenceContext and the like) and CDI's brand of dep...
I have noticed from several web pages that apparently Spring 3.0 supports @Inject from JSR-330. As we would really like to use JSR-299 syntax for dependency injection in our libraries for both web apps and stand-alone applications, and have alternatives to Weld, it would be nice if Spring could do this. Being a novice to Spring, I trie...
In a managed bean, @PostConstruct is called after the regular Java object constructor. Why would I use @PostConstruct to initialize by bean, instead of the regular constructor itself? ...
I am new to weld and consider what environment is useful for a web-application using CDI (Weld). I want to use JSF or Wicket for presentation and JPA/Hibernate for my persistence layer (including Transaction-Management). The obvious scenario is to use a JBoss or Glassfish application server with EJB3 surrounding, but is there not a chanc...
