Utilisation de JSP avec Jetty intégré 7 dans Eclipse IDE, obtenir LogConfigurationException

Question

J'ai inclus tous les pots nécessaires à l'application, je suis en train d'utiliser la jetée intégrée

J'ai une simple classe java avec une méthode principale qui a la Après l'installation, les servlets fonctionnent toujours correctement et ne peuvent pas faire fonctionner les JSP. Tous les jars requis sont inclus, démarrés avec les jets Jetty de base, puis ajoutés dans le répertoire jsp.

Server server = new Server(8080); 

WebAppContext context = new WebAppContext(); 
context.setDescriptor("WebRoot/WEB-INF/web.xml"); 
context.setResourceBase("WebRoot/"); 
context.setContextPath("/"); 
context.setParentLoaderPriority(true); 

server.setHandler(context); 

server.start(); 
server.join(); 

Erreur:

Answer 1

Il est très probable d'être une classe manquante.

Je suis essentiellement le même extrait de code pour travailler sous Maven construire avec

<dependency> 
     <groupId>org.eclipse.jetty.aggregate</groupId> 
     <artifactId>jetty-all</artifactId> 
     <version>7.2.0.v20101020</version> 
     <type>jar</type> 
     <scope>compile</scope> 
    </dependency> 
    <dependency> 
     <groupId>org.mortbay.jetty</groupId> 
     <artifactId>jsp-2.1-glassfish</artifactId> 
     <version>2.1.v20100127</version> 
     <type>jar</type> 
     <scope>compile</scope> 
    </dependency> 

et log4j.

Answer 2

Je préfère utiliser l'artefact jetée-jsp avec la jetée agrégée-tout serveur, comme les deux sont disponibles de la même version de la jetée:

<dependency> 
     <groupId>org.eclipse.jetty.aggregate</groupId> 
     <artifactId>jetty-all-server</artifactId> 
     <version>${jetty.version}</version> 
    </dependency> 
    <dependency> 
     <groupId>org.eclipse.jetty</groupId> 
     <artifactId>jetty-jsp</artifactId> 
     <version>${jetty.version}</version> 
    </dependency> 

Je l'ai testé avec la version 7.6.12 Jetty .v20130726, les deux dépendances sont disponibles sur Maven central repo.
