J'ai de grands doutes sur ce forum, mais je suis prêt à être agréablement surpris;) Félicitations et bon karma à ceux qui me remettent sur la bonne voie.Utilisation de l'implémentation Blitz de JavaSpaces
Je tente d'utiliser la mise en œuvre de blitz de JavaSpaces (http://www.dancres.org/blitz/blitz_js.html) pour mettre en œuvre l'exemple ComputeFarm fourni à http://today.java.net/pub/a/today/2005/04/21/farm.html
Le dans l'exemple de la mémoire fonctionne très bien, mais chaque fois que je tente d'utiliser le blitz out-of-box la mise en œuvre que je reçois l'erreur suivante:
(oui com.sun.jini.mahalo.TxnMgrProxy
est dans le chemin de classe)
