Question

I want to write in an xml file located under the conf directory of jboss.

I open it like this:

public void initialiserXml() {
        sxb = new SAXBuilder();

        try {
                    String fileXml= System.getProperty("jboss.server.home.dir").concat("/").concat("/conf").concat("/exempleMessage.xml");
            System.out.println("Fichier xml " +fileXml);
            document = sxb.build(fileXml);
            racine = document.getRootElement();
            System.out.println("Fichier Xml trouvé");
        } catch (FileNotFoundException e) {
         System.err.println("Aucun fichier XML trouvé");
        } catch (JDOMException e) {
             System.err.println("Fichier XML mal construit");
        } catch (IOException e) {
             System.err.println("Impossible d ' ouvrir le fichier XML");
        }
   }

and after modification i write the change like this

public void enregistreFichier()
   {
         XMLOutputter sortie = new XMLOutputter(Format.getPrettyFormat());
         try {
            sortie.output(document, new FileOutputStream(fileXml));
        } catch (FileNotFoundException e) {
             System.err.println("Fichier XML source non trouvé");
        } catch (IOException e) {
             System.err.println("Impossible d ' ecrire dans le fichier XML");
        }
   }

This works on my test environment, but when I test this on a production environment (Linux server), it no longer works when
i pass on sortie.output(document, new FileOutputStream(fileXml));
(FileNotFoundException)

I don t understand , my file is found when i open it with saxbuilder , but when i write in , i have a filenotfoundexception

How to solve the problem please?

thank you very much

Answer 1

FileNotFoundException is also thrown when you don’t have all needed permission’s to the file. In this case you might be missing write permission from /conf/exempleMessage.xml file

You should check which user is running jboss by giving command “ps -ef | grep jboss”, it gives you a list all process witch name contains string jboss. After this you change ownership of file to that user by “chown : /conf/exempleMessage.xml”
