Hi guys,
I am using Nutch 0.8.1, for the past 2 days I have been getting the
following exception: Java.Lang.IllegalStateException. The exception started
after I implementing the Nutch-61 patch; Adaptive Re-crawl Interval. In
short, this happens:
I am trying to crawl XML files (locally and remotely on a web server), once
crawl, the fetcher sends the file to their processing parsers. This is where
the exception is thrown as the parsers launches but do not perform any
activity on the file. If anybody has dealt with this type error, please let
me know how to get rid of it. Below is an extract from my log file.

If a root element is not set within an XML file, a nullpointer exception is
thrown not an illegalstateexception. #can anyone put some lights on this
error.
Thanks.
