j'ai crée mon fichier report.jrxml sous ireport4 je l'ai compilé et exécuté ,et sa marche zen avec un paramètre que j'ai donné ,et mon rapport marche bien.
ensuite j'ai ajouté le fichier compilé report.jasper et le fichier PDF report. PDF dans un dossier sous "web pages" de projet .
lorsque je run ma jsp , je saisie le paramètre et je clique sur le bouton "generate" ,il me redirige vers une page vide .et lorsque je verifie le log serveur je vois l'erreur suivante
