Lorsque je tente de lancer mon webapp sur MyEclipse Tomcat, j'ai eu l'exception suivante:java.lang.LinkageError: loader violation de contrainte (projet déploiement)

java.lang.LinkageError: loader constraint violation: when resolving interface method "javax.servlet.jsp.JspApplicationContext.getExpressionFactory()Ljavax/el/ExpressionFactory;" the class loader (instance of org/apache/catalina/loader/WebappClassLoader) of the current class, com/sun/faces/config/ConfigureListener, and the class loader (instance of org/apache/catalina/loader/StandardClassLoader) for resolved class, javax/servlet/jsp/JspApplicationContext, have different Class objects for the type javax/el/ExpressionFactory used in the signature

Il semble que les problèmes sont causés par manque jarres ou le serveur

Vous avez deux dépendances définies pour

<groupId>javax.el</groupId> 
    <artifactId>el-api</artifactId>

avec des versions différentes. Cela pourrait être au moins une partie de l'erreur. Essayez de supprimer l'une des dépendances.

Nous vous remercions de votre réponse. J'ai résolu le problème. Je viens de supprimer le servlet-api et el-api du dossier lib dans mon répertoire tomcat –

Pas de problème. Si ma réponse m'a aidé, considérez au moins de le voter. Merci. –
