Les librairies dans mon projet (sous eclipse):
commons-beanutils.jar,commons_collections.jar,commons-digester.jar, commons-fileupload.jar, commons-lang.jar,commons-logging.jar, commons-validator.jar, jakarta-oro.jar, struts-legacy.jar,struts.jar

Et en fin voici les erreurs que j'obtiens (sous Tomcat).
J'obtiens des erreurs aussi sous JBoss.
