iText5.1.0 en-tête et pied de page dans le document

Oublier les servlets pour une seconde. Assurez-vous que vous pouvez obtenir de l'en-tête/pied de page à l'œuvre localement.

Edit: j'ai été un mauvais de SORTE que l'utilisateur en affichant sur obsolètes HeaderFooter choses. Il semble que beaucoup de gens font cela, il est extrêmement difficile de trouver succincte des exemples de cette question. ajouter un en-tête au format pdf avec iText répond à cette question.

Ici semble être la bonne façon de le faire: (Modifié à partir de http://itextpdf.com/examples/iia.php?id=104 ):
