Solr + nutch + distributed search

hi all,

i am in the process of integrating nutch and solr;

I am trying to call the solr server from the NutchBean and getting an
exception which seems to show that nutchBean is trying to read the local
index not solr server.

not sure whats missing in my config for me to be able to get my search
results from solr server?

the only thing i did was to drop a solr-servers.txt inside the crawl
folder.

here is the exception:

11:06:02,585 ERROR [NutchBean] Exception occured while executing search:
