Bonjour.

Je viens à vous car je suis face à un problème qui me bloque plutôt bien.

Dans mon application, je réalise des imports et des exports de fichier csv et xml. Les fichiers sont enregistrés dans ma base en tant que blob.

Lors d'un export, mon fichier est créé en batch et enregistré dans la base.
Afin de le récupérer, j'utilise un bouton de download qui me permet de récupérer le fichier créer.

Pour ce faire j'utilise le code suivant:

                dataWriter.write(sb.toString());
                // Close writer and reader
                dataWriter.close();
                reader.close();
            }

            FacesContext.getCurrentInstance().responseComplete();
            sLogger.info("after response complete.");

            .getResponse();
 
        response.setHeader("Pragma", "no-cache");
        response.setDateHeader("Expires", 0);
        response.setContentType(mimeType);
        response.setHeader("Content-disposition", "attachment; filename=" + fileName);
        if (mimeType.equals("text/xml"))
            response.setCharacterEncoding("utf-8");
 
        return response;
    }

Tout ceci fonctionne parfaitement lorsque je télécharge un fichier.
Le problème viens du fait que lors d'un téléchargement en cours d'un fichier d'une taille assez conséquentes, si je rééssaye de télécharger le fichier, j'ai l'erreur suivante:

J'avoue que je je bloque un peu sur cette erreur si quelqu'un a une idée?

[luminien]

Salut,
Il s'agit d'un heap space (manque d'espace mémoire) et si tu allouais à ton serveur plus de mémoire !!
en ajoutant l'argument -Xms256M -Xmx512M à ton serveur !!!

[anisj1m]

si tu as assez de mémoire tu peux ajouter

Code :

-Xms512m -Xmx1024m -XX:MaxPermSize=512m

aux arguments de ton serveur
