Hi all,
I have deployed my portlets on WSRP4J producer. Everything seems to work
fine, cause I can get the service description from the producer. However,
when I request for the markup response, I always get "Error occurred while
invoking portlet service." This is the stack trace from wsrp4j producer:

Could any one please help me to figure out what's wrong.
Thanks so much.
