Erreur HTTP 404: (/ SpringMVC /) indisponible

Question

ressource J'ai installé:

-eclipse Indigo 3.7, 
-JDK 1.7 in /usr/lib/jvm` and, 
-Tomcat 7 
-Spring framework 2.5.6 

Je suis en train de faire un tutoriel found here:

Pour que j'ai créé un «dynamic web project» fait avec «Spring MVC framework». J'ai essayé de le faire en faisant «Run on server» mais j'ai obtenu un «HTTP 404 error: (/SpringMVC/) ressource unavailable». Je ne sais vraiment pas ce qui me manque. Merci d'avance pour toute aide.

Ce sont les bibliothèques que j'avais d'abord inclus dans le projet:

-jakarta-commons/commons-logging.jar 
-mysql-connector-java-5.1.18 
-j2ee/jstl.jar 
-log4j/log4j-1.2.14.jar 
-jakarta-taglibs/standard.jar 
-dist/spring.jar 
-dist/modules/spring-webmvc.jar 

Je viens d'ajouter la bibliothèque spring-web.jar.

Ceci est le nouveau message d'erreur que j'ai:

Answer 1

java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

vous semble ne pas inclure la dépendance à ressort web.jar au classpath (dans WEB-INF/lib).
