org.apache.nutch.protocol.ProtocolNotFound: protocol

[Arun Kaundal <ar...@gmail.com>]

Nutch Geeks-

   I am facing problem with parsing, as protocol for parsing of particular
type of file is not found. How do I parse the content of those files?
What configuration changes are require (if any ) or Is it problem with
particular library . Please send your reply asap. Thanx a ton

Complete log is attched in errorlog.txt file
