Hi,

I'm learning Struts2, I had all struts2 libraries in WebInf/lib
here yu get my web.xml :

	<display-name>GestionDeveloppeur</display-name>
	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>
		org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
		</filter-class>
	</filter>

	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
</web-app>

The Struts.xml file

<struts>
	<constant name="struts.enable.DynamicMethodInvocation" value="false" />
	<constant name="struts.devMode" value="false" />
	<package name="com.developpez.actions" namespace="/"

		<default-action-ref name="saisir_Developpeur" />

Is it WEB-INF/lib or WebInf/lib you are using?
Is struts2-core-2.x library added in class path?
