Help needed with Weld,EJB,JSF
Hi everybody,
I am hitting an issue I cannot resolve alone, for which I'd be very glad and thankful getting some help and input.
I am trying to implement a registration system in JSF using a service exposed via Weld. The service is a staful session bean exposed via CDI to jsf. It has a producer method, producing a new request-scoped User instance, and a register
method, persisting the jsf-filled user instance. So far so good (or is it?)
The thing is that any call from jsf to the register
method raises an IllegalStateException. Here is the code
Bean :
@Named("registration")
@SessionScoped
@Stateful
public class RegistrationService implements Serializable {
@Inject @Named("newUser")
User newUser;
@Inject @UserDatabase EntityManager em;
@Produces @RequestScoped @Named("newUser")
public User getNewUser()
{
return new User();
}
public String register() {
em.persist(newUser);
return null;//"registerConfirmation";
}
}JSF page snippet :
<h:form>
<h1><h:outputText value="Create/Edit"/></h1>
<h:panelGrid columns="3">
<h:outputLabel value="Username:" for="username" />
<h:inputText id="username" value="#{newUser.username}" title="Username" />
<h:message for="username"/>
<h:outputLabel value="Email:" for="email" />
<h:inputText id="email" value="#{newUser.email}" title="Email" />
<h:message for="email"/>
<h:outputLabel value="Password:" for="password" />
<h:inputSecret id="password" value="#{newUser.password}" title="Password" />
<h:message for="password"/>
<h:commandButton value="Ok" action="#{registration.register}"/>
</h:panelGrid>
</h:form>
Does anything seems weird to you ?
What would you advice as best practice (regarding Statefulness, Scoping...) to implement a registration system ?
Anyway, thanx to ya if you read this far :)
