problem with managed bean

[kamel ben Mbarek]

hi
i'm new here and i'm trying to learn how to develop using j2ee .. i have encountred a problem when using managed beans . the idea was that i'll make one managed bean for each (xhtml) page but the problem is ; i can't access information contained in one managed bean from another ..

it's a simple login then redirection to home page . so can any body give me a hint on how to save the user information during his session and access them from anywhere class i want .

please help
thank you


p.s i'm using jsf 2.0 on glassfish 2.0 server

Yo can acces a session beans from another bean with below code.

MyBean mb = (MyBean) FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("myBean");

Hi Kamel

You can use the option of Abdulkerim is very well, but it suppose that your bean must be a Session Scope, I want to give you another option to make the same thing:

FacesContext context = FacesContext.getCurrentInstance();
YourBeanClass result = context.getApplication().evaluateExpressionGet(context, "#{yourBeanName}", YourBeanClass.class);

Regards

thank you guys for your help. i found this solution using annotation :

    @ManagedProperty(value="#{login}")
     login currentLogin;
     public void setCurrentLogin(login newValue) { currentLogin = newValue; }
