Class not found with Struts2 and Netbeans - netbeans

Question

I'm using Netbeans 7.1, and i try to include Struts2.3.14.3 in my J2EE project.
I tried to :
put the .jars in the WEB-INF/lib path
link the .jars in the libraries "folder" of the project in Netbeans
create a librarie including the .jars and link it to the project
But none of these solutions work, when i deploy the application on my Glassfish server it keeps rising these kind of error :
Grave: Dispatcher initialization failed

You need a structure like this:
YourEar.ear
lib
library1.jar
library2.jar
libraryN.jar
META-INF
YourWar.war
jsp
jsp1.jsp
jsp2.jsp
jspN.jsp
META-INF
WEB-INF
lib
libraryA.jar
libraryB.jar
libraryX.jar
classes
your.package.your.classes.etc...
struts.xml
web.xml
Struts libraries goes inside war, not ear (libraryA, B, X...)
Open the generated ear/war and check thet everything is on its right place.
