I am doing remote staging but i am facing this problem. Some portlets do work fine and they got transfered from staging to production system but in some this problem appears. I have only one system so i am running two instances of tomcat, one is running on port 8080(staging) and one on 8081(production). When i transfer my portalet then on staging side i got the following exception.
while on the production side i got a number of exception so here are some.
