managed-bean

I'm planning to convert a web app from using JSF managed bean to using CDI managed beans. I know I'll need to do below: Add a empty beans.xml file in WEB-INF. Replace all JSF @ManagedBean to CDI @Named annotations. Replace all JSF scope annotations with CDI or OmniFaces scope annotations. Replace all JSF @ManagedProperty with CDI @Inject annotations. Is that all that needs to be done? Are there any gotchas that I need to be aware of? Basically, that's indeed all you need to do provided that you're on a Java EE server already. When on Tomcat, you'd need to manually install CDI first.

I have a stateless EJB and two different SessionScoped managed beans. e.g. EJB as follows - @Stateless public classs MyEjb implements MyEjbLocal { @PersistentContext(unitName="myPU") private EntityManager em; and a managed bean - @ManagedBean @SessionScoped public class MyBean1 implements Serializable { @EJB private MyEjbLocal myEjb; and another managed bean - @ManagedBean @SessionScoped public class MyBean2 implements Serilizable { @EJB private MyEjbLocal myEjb; private List<MyEntity> entities; public MyBean2() { entities = myEjb.getAllEntities(); //this is where the problem is, myEjb is null

I have 2 JSF managed beans A and B and I need to expire/destruct/destroy A after 2 minutes and B after 5 minutes. I checked this related question Timing out from a bean , but it is expiring whole session. I do not want to expire whole session. How can I achieve this with a custom scope? Given that you're using JSF bean management facility (and thus not CDI, which would require a completely different answer), you can achieve this with @CustomScoped . The @CustomScoped value must refer a Map implementation in a broader, usually existing, scope. Something like: @ManagedBean @CustomScoped("#

i would like to know if there is a way to fire a jsf managed bean method (with an AjaxBehaviorEvent type parameter: the same triggered when using f:ajax) directly by using a jquery ajax server request.By the way , i m a jsf developper and i didn't find an example about using jquery ajax with Java EE as a server-side framework, all examples i found were with php..so i wish to get a complete example about doing that. i think the other workaround maybe is to make a commandLink being submitted with jquery on the client side and passing parameters through that call but i prefer the former solution

This question already has an answer here: Backing beans (@ManagedBean) or CDI Beans (@Named)? 5 answers Okay, so I have a JSF backing bean that needs a reference to another (@NoneScoped) bean. Should I @Inject it or use @ManagedProperty to obtain an instance reference from the container? Why use one and not the other, in my mind the two approaches achieve the same thing. @ManagedProperty and @NoneScoped comes from the JSF 2.0 spec whilst @Inject comes from the CDI spec. If you are just working on a servlet application that doesn't make any use of any of the others JavaEE 6 features, then go

I have a managed bean (SessionScope as follow) @ManagedBean(name="login") @SessionScoped public class Login implements Serializable { private String userSession; public Login(){ } } In this managedbean, somewhere in the login function, i store the email as a session. I have another managed bean called ChangePassword (ViewScoped). I need to access the value of the email which is stored in the userSession. The reason of doing so is that i need to find out the current userSession(email) before i can complete the change password function. (Need change password for that specific email) How do i do
