When i ran this program i am getting the following error

Now i have added the 

  | <protocol_stacks>
  | 	<stack name="udp"
  | 		description="Default: IP multicast based stack, with flow control and message bundling">
  | 
to jgroups.xml. When i ran the program, its giving the following error.


  | log4j:WARN No appenders could be found for logger (org.jboss.cache.util.FileLookup).
