[Résolu] Runtime.exec avec Alfresco 3.4d

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Hello,

Une de mes actions exécute des commandes externes (transformation d'image, détection de code-barres). Tout fonctionne à merveille avec Alfresco 32r2 et 3.3g sur Windows et Linux.
J'aimerais mettre à jour pour 3.4d mais j'ai des problèmes sous Linux… (tout est ok sous Windows).

Dans mon action

…
Process proc = Runtime.getRuntime().exec(commands);

Une autre commande…

[/bin/sh, -c, /usr/local/bin/zbarimg -q -Sdis -Sqrcode.en "/opt/Alfresco/tomcat/temp/Alfresco/ReadBarcodesSplit45676289/0_splitted.pdf_A.gif"]‍

Error execution stdError

zbarimg: magick/cache.c:647: AcquireOnePixelFromCache: Assertion `image != (Image *) ((void *)0)' failed.‍

Les commandes effectuées sur le serveur fonctionne.

Y-a-t'il eu des nouveautés liées au Runtime.getRuntime() ? Dois-je configurer autrement Tomcat ?

Je remarque aussi avec la 34d que je dois préciser l'emplacement du programme (zbarimg) avec /usr/local/bin/ (j'ai un message qui me dit qu'il ne trouve pas le programme). Cela n'était pas le cas avant… Il semble que des variables ne sont pas accessibles depuis le tomcat…

Merci bien

J'ai refait des tests…. Si j'exécute la commande sur la machine directement ou par un programme java, tout fonctionne, mais pas depuis Alfresco. Si j'utilise le convert inclu dans Alfresco, cela me provoque une autre erreur… mais pour le moment je vais tenter de faire fonctionner le "convert" installé sur la machine (qui fonctionnait avant avec Alfresco 32r2 et 33g).
