Déploiement de gwt-dev.jar sur Glassfish (NoClassDefFoundError)

Question

Sur le côté serveur de mon application GWT, j'utilise des classes du package org.apache.commons.httpclient. Ces classes sont commodément emballées dans gwt-dev.jar distribué avec GWT. J'inclus ce pot (le long du gwt-servlet.jar) dans le WEB-INF/lib de la guerre. Lors du déploiement du fichier de guerre produit sur GlassFish et appelant la page que je reçois l'exception suivante dans les journaux du serveur (et un RPC manquai)

NoClassDefFoundError: org/apache/commons/httpclient/HttpException 

Que dois-je faire pour que GlassFish trouve les classes dans le gwt-dev.jar?

- plus de détails -

En tant SSCCE qui reproduit le problème, je l'ai modifié la classe GreetingServiceImpl de l'exemple GWT:

import org.apache.commons.httpclient.HttpException; 
public String greetServer(String input) throws IllegalArgumentException { 
     try { 
      if(input.equals("hello")){ 
       throw new HttpException(); 
      } 
     } catch (HttpException e) { 
      throw new RuntimeException(e); 
     } 
     ... the rest of the GWT example app

Vous devez ajouter les communes-httpclient.jar (ou httpclient-4.0.1.jar - dépend de la distribution) à votre 'répertoire WEB-INF/lib'.
