Session Bean ne fonctionne pas

Question

J'ai un SessionBean et je veux charger des données à partir d'une classe InfoHolder appelée Benutzer. Mais ça ne marche pas.

    public void setUser(String user) {

    } 

Cela ne fonctionne pas. Mais quand j'utilise bntzr ... alors rien ne marche plus:/ Y a-t-il un exemple non trivial?

Answer 1

Utilisez ceci: group52.infoholders.Benutzer.

Y at-il des fonctions getter et setter, comme: public Benutzer getBenutzer() {return bntzr; } public void setBenutzer (Benutzer bntzr) {this.bntzr = bntzr; }
