Bonjour,
J'ai un problème lors d’exécution d'un projet:
c'est ça qui m’affiche dans le console:
com.kwoksys.framework.servlets.RequestProcessorServlet process
SEVERE: Problem processing request filter.
java.lang.ClassCastException: org.apache.catalina.connector.ResponseFacade cannot be cast to javax.servlet.ServletRequest
at com.kwoksys.framework.servlets.RequestProcessorServlet.process(RequestProcessorServlet.java:77)
...
et voici le code source de classe RequestProcessorServlet sachant qu'il ne signale pas des erreurs au niveau de cette classe.
