Hello guys,
I have to use this proxy class in order to avoid concurrent calls exception (http://java.sun.com/blueprints/guidelines/designing_enterprise_applications/ejb_tier/qanda/#prevent):
public class CommentDAOImpl {
private LocalCommentDAO commentDAO;
public CommentDAOImpl() {
this.commentDAO = (LocalCommentDAO) Contexts.getConversationContext().get(CommentDAO.class);
System.out.println("context= " + Contexts.getConversationContext());
System.out.println("setted commentDAO= " + commentDAO);
}
...
}
CommentDAO looks like this:
@Stateful
@Name("commentDAO")
@AutoCreate
public class CommentDAO implements LocalCommentDAO {
...
}
But when I call the constructor of CommentDAOImpl, the commentDAO component is reported as null, even if the class is marked with @AutoCreate:
14:55:18,015 INFO [STDOUT] context= ConversationContext(3)
14:55:18,015 INFO [STDOUT] setted commentDAO= null
If I use the @In annotation to inject the commentDAO component in some other stateful components, it works ok and the commentDAO component is created.
So, what is the difference between the @In private LocalCommentDAO; annotation and the Contexts.getConversationContext().get(CommentDAO.class) calls? How can I create a component when it is injected through Contexts.getConversationContext().get(CommentDAO.class)?
Thank you in advance,
Bogdan.
