Autorisation Tomcat refusée lors de la tentative d’écriture d’un fichier

J’essaye d’envoyer un zip via le serveur tomcat. Mais quand j’essaie d’accéder à http: // localhost: 8094 / fetna-project-rest / webapi / retdoc / 10 J’ai reçu une erreur de permission que j’ai incluse dans le bas. Je lance le serveur sur Ubuntu. Pouvez-vous m’aider s’il vous plaît? Mes codes sources sont ici:

public static void addToZipFile(Ssortingng fileName, ZipOutputStream zos) throws FileNotFoundException, IOException { System.out.println("Writing '" + fileName + "' to zip file"); File file = new File(fileName); if (!file.exists()) { file.createNewFile(); } FileInputStream fis; fis = new FileInputStream(file); ZipEntry zipEntry = new ZipEntry(fileName); zos.putNextEntry(zipEntry); byte[] bytes = new byte[1024]; int length; while ((length = fis.read(bytes)) >= 0) { zos.write(bytes, 0, length); } zos.closeEntry(); fis.close(); } @GET @Path("retdoc/{id}") @Produces(MediaType.APPLICATION_OCTET_STREAM) public Response resortingeveDocument(@PathParam("id") Ssortingng ID) throws IOException { FileOutputStream fos = new FileOutputStream("test.zip"); ZipOutputStream zos = new ZipOutputStream(fos); Ssortingng file1Name = "test.txt"; addToZipFile(file1Name, zos); zos.close(); fos.close(); File zippedFile = new File("test.zip"); return Response.ok(FileUtils.readFileToByteArray(zippedFile)) .type("application/zip") .header("Content-Disposition", "attachment; filename=\"resortingevedDocuments.zip\"") .build(); }

et mon stacktrace:

L’utilisateur qui exécute tomcat n’est pas autorisé à écrire le fichier, comme le dit l’erreur. Nous vous suggérons de choisir un dossier spécifique dans lequel vos fichiers téléchargés seront enregistrés et de donner à l’utilisateur de tomcat des droits d’écriture (modifiez le nom d’utilisateur et le chemin en conséquence):

 $ sudo mkdir /home/tomcat/uploads $ sudo chown tomcat:tomcat /home/tomcat/uploads $ sudo chmod u+wrx /home/tomcat/uploads

Puis changez votre code de servlet pour utiliser le chemin de téléchargement (ligne modifiée ci-dessous):

 FileOutputStream fos = new FileOutputStream("/home/tomcat/uploads/test.zip");
