java.lang.ClassNotFoundException <rfc> Found in negative cache

[Former Member]

Hi,

I need help for this dump seen on portal for one of the applications.

I have been checking on sdn and there are several threads on it which suggest redeploy, restart j2ee etc

But nothing is working.

This problem started when the portal system was changed from A to B for a backend system C.
