MyFaces Context Loading troubles - jsf

Question

I met in several times a problem to load myfaces context, i've solved it by recreating maven project like these : mvn eclipse:clean eclipse:eclipse, whithout knowing the real cause, now i am blocked because the problem has reappeared, here is the details :

Answer 1

I was having the same error you did, when I saw this post, which solved it.
Basically, my build was accidentally adding javax.servlet-5.1.12.jar and jsp-api-2.1.jar, that were coming into conflict against Tomcat's implementations of these same APIs.
Maybe one of those gt-*.jar files would happen to be a copy of the servlet/jsp libraries?
