@Inject converting to @PersistenceContext HOWTO?

[jeremyc]

I am new to EJB 3.0 and I went through the tutorial of the EJB 3.0 TrailBlazer and found that it uses @Inject and that has been removed from the spec. I found briefly where it says to use @PersistenceContext but I am having no luck. The class is simple in the TrailBlazer:

public @Stateless class AuthorsBean implements Authors {
 @Inject
 private EntityManager manager;

 public void addArticle(Author author, String title, String body) {
 manager.persist(author);

 author.addArticle(title, body);
 }

 public Author addAuthor(String name) {
 Author author = new Author();
 author.setName(name);

 return author;
 }

 public List<Author> getAllAuthors() {
 ArrayList<Author> authors = new ArrayList<Author>();

 Query q = manager.createQuery("from Author");
 for (Object o : q.getResultList())
 {
 authors.add((Author) o);
 }

 return authors;
 }

}

How would I convert this to function correctly?

Thanks,

Jeremy
