ImageDisplay et Panner non reconnu

salut

je débute avec JAI et j'ai pris le tutoriel ImageViewer à cette adresse http://java.sun.com/developer/online...jai/index.html et j'ai essayé de l'exécuter sur eclipse mais il ne reconnait pas ImageDisplay et Panner.

est ce que qqn a une idée? car j'ai installé JAI sur eclipse


merci
