salut
je travaille avec maven 2 et gwt 2.0.0 et gxt sl1.1
la version de java est jdk1.6 update17
tout fonctionne bien, j'ai copié mon application pour l'importer sur mon labtop mais c'est maintenant que j'ai des problémes que je n'arrive pas à résoudre.
Au moment de l'exécution(gwt:run), cette erreur est affiché:
Code : Sélectionner tout - Visualiser dans une fenêtre à part
