Today I opened my project and after deploying it I had this exception:

ERROR [Digester] Begin event threw error
java.lang.NoClassDefFoundError: org/ajax4jsf/resource/InternetResource
ERROR [STDERR] javax.faces.FacesException: org.ajax4jsf.renderkit.ChameleonRenderKitFactory

Yerterday I had no problem with it, and I didn't changed anything...
Anyone knows??
