How to redirect after login?

Question

I've username and password bound to the backing managed bean. In the backing bean, when I check the username and password with DB, I want to redirect the page from login.xhtml to home.xhtml. How can I do that?

Answer 1

Just return the view ID appended with faces-redirect=true parameter.

E.g.

public String login() {
    User found = userService.find(username, password);

    if (found != null) {
        this.user = found;
        return "home?faces-redirect=true"; // Will redirect to home.xhtml.
    }
    else {
        addGlobalErrorMessage("Unknown login, please try again");
        return null; // Will stay in current view (and show error message).
    }
}
