probleme avec rtfTemplate pour application web
Bonjour ,
J'essaie de mettre en place la génération de document avec rtfTemplate , en y allant par étape.
En un premier lieu mon but est simplement éditer un document .rtf qui ne contient que du texte( sans les objets java que je ferais en second lieu )i.e. avoir la fenetre qui s'ouvre(ouvrir, enregistrer..).
j'utilise struts et lorsque que je suis dans ma jsp je clique sur une image qui apelle la methode valider de mon action et celle-ci fait un forward pour lancer ma servlet TestSC1 qui hérite de AbstractRTFTemplateServlet.
voici le code de TestSC1:

J'ai utilisé l'exemple qu'il y avait dans la distribution rtftemplate-web-usecases-1.0.1-b14 en mettant en dur le nom de mon fichier pour mon premier test.
Mon souci est que quand je lance cette servlet j'obtient cette erreur :

J'ai fait pas mal de recherche dans les forums et apparemment getWriter() a déjà été appelé dans la jsp pour instancier l'objet out.
Je me dis donc que je m'y prends mal pour implémenter rtfTemplate dans une appli web.
Si quelqu'un pourrais m'éclairer car ma jsp est mon point de départ et si j'ai bien compris j'ai besoin de cette servlet.
Voilà pour plus d'information le reste de mon code :

Merci pour vos réponses.
De mon coté je continue à chercher .
