Re: nutch 2.x nutchserver problem

[Lewis John Mcgibbney <le...@gmail.com>]

Hi Paul,

I cannot reproduce this initialization error... I show this as follows
using 2.X from SVN

lmcgibbn@LMC-032857 /usr/local/2hbase(joshua) $ svn status
lmcgibbn@LMC-032857 /usr/local/2hbase(joshua) $ svn update
Updating '.':
At revision 1722842.

lmcgibbn@LMC-032857 /usr/local/2hbase(joshua) $ ./runtime/local/bin/nutch
nutchserver
Starting NutchServer on port: 8081 with logging level: INFO ...
Starting the internal [HTTP/1.1] server on port 8081
Started NutchServer on port 8081

When I start the webapp on port 8080 I also get no errors!
Can you please make sure that you pull the code from the canonical source
when resides at
http://svn.apache.org/repos/asf/nutch/branches/2.x/
