Storing user Information

Question

Hi Guys and Girls,
I am trying to store user information. I retrieve the user ID by the following code:
public String getUser() {
        FacesContext ctx = FacesContext.getCurrentInstance();
        HttpServletRequest request = (HttpServletRequest)ctx.getExternalContext().getRequest();
        //return (String)request.getAttribute("User");
        return (String)request.getSession().getAttribute("User");
    }Through out the application I will need the userId, username, email, admin status. I would like to retrieve this information once and be able to reference it. My first thought is a stateful session bean. But I am not sure if this is the best approach and I am also not sure exactly how to set the values. Do I put the above code into the bean or do I set the values in the bean from my opening jsf page. If someone could give me some direction with some code examples it would be very helpful. Thank you.

Use a session scoped managed bean.
Something like:public void login() {
    User user = UserDAO.getUser(username, password);
    if (user != null) {
        FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("user", user);
    } else {
        // Handle.
public void logout() {
    FacesContext.getCurrentInstance().getExternalContext().getSessionMap().remove("user");
}Userpublic static User getCurrentUser() {
    return (User) FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("user");
}Any beanpublic void doSomething() {
    User currentUser = User.getCurrentUser();
public void isLoggedIn() {
    return User.getCurrentUser() != null;
}faces-config:<managed-bean>
    <managed-bean-name>user</managed-bean-name>
    <managed-bean-class>mypackage.User</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
</managed-bean>JSF<h:outputText value="Welcome, #{user.name}" rendered="#{bean.loggedIn}" />
