How does it relate to Java EE 6? JSR-299 is part of Java EE 6 (JSR-316). How would one use … Read more

Combining my attempts with an answer from the Weld forum: @Inject @Any private Instance<SocialNetworkService> services; Instance implements Iterable, so it is then possible to simply use the for-each loop. The @Any qualifier is needed. Another way to do this is by using the event system: create a MessageEvent (containing all the information about the message) … Read more

Below a longer explanation from Gavin King: Re: Comparisons to @ManagedBean annotations in JSF2?: While looking through the Weld examples, and the older WebBeans documentation, it looks like a competitor to the new @ManagedBean JSF … Read more
Before trying to answer your question, let me just add an important piece of information: JSR 330 (@Inject) was standardized by Guice and Spring projects (announcement from May 2009) and is being reused in JSR 299. This covers basic DI mechanisms in terms of declaring an injection point. Now, back to the question – with … Read more
For EJB and JAR packaging you should place the beans.xml in src/main/resources/META-INF/. For WAR packaging you should place the beans.xml in src/main/webapp/WEB-INF/. Remember that only .java files should be put in the src/main/java and src/test/java directories. Resources like .xml files should be in src/main/resources.
You can make your bean passivation capable by implementing the Serializable interface: public class DemoBean implements Serializable { … } Note that there are more requirements for being passivation capable. Refer to the Weld documentation for more information.
