Error in deploying jsf application

[Gabriele Morelli]

Hi, i found your email on mail-archives.org and thought to write you because I am getting an error as I deploy my jsf application, this is the error:   org.apache.jasper.JasperException: The absolute uri: http://myfaces.apache.org/extensions cannot be resolved in either web.xml or the jar files deployed with this application D:\Schede285_jsf\nbproject\build-impl.xml:330: Java returned: 1   Do you have any clue of what it might be? Thank you for you time.   -=GAB=-
