J'ai donc installé je JDK 1.7.0_40

et j'ai essayer de compiler avec javac.

Voilà si quelqu'un arrivais à me faire marcher ce code ça serait vraiment sympa.
C'est un programme qui permet de signer des documents XML à partir d'un certificat digital se trouvant sur un token (smartCard).

Merci d'avance

une classe public par fichier. Par exemple, le fichier Toto.java contiendra la classe public Toto (éventuellement d'autre classe, mais pas public).
Dans ton cas, par exemple, dans le fichier X509KeySelector.java, tu auras la déclaration public class X509KeySelector:
