error in <a4j:mediaOutput

[orkun]

hello

Although I loaded jsf-facelets jar in my library path, I received this exception:

SEVERE: Error instantiation parent Faces ViewHandler
java.lang.ClassNotFoundException: com.sun.facelets.FaceletViewHandler


in using:

<a4j:mediaOutput element="img" cacheable="false" session="true"
createContent="#{mediaBean.paint}" value="#{mediaData}" mimeType="image/jpeg" />


what jmay be the reasons

regards

Hello,

Do you have javax.el package in your classpath?
