error procssing gravityRequest in tomcat 7

Question

I configured a java/flex web app using granite ds. the gravity servlet is configured well in web.xml .

when the gravity request hits the server I have this error (log message in tomcat) :

500 returned for /Migration/gravityamf/amf with message org.apache.catalina.CometProcessor

and the cause was :

java.lang.ClassNotFoundException: org.apache.catalina.CometProcessor

does this error means some path i can dig into it.

Answer 1

That application has been written for Tomcat 6 and won't run on Tomcat 7 without being modified to use the new package for the Comet classes.
