[Archive-access-discuss] java.lang.RuntimeException: java.lang.NullPointerException

[roger p <ro...@ho...>]

Can anyone tell me howto overcome the following problem.

I use:
Fedora Core 5
Sun Java 1.5

and I have followed the instructions throughout the manual, but still I get 
an error retrieving the records in the arc files. The following error 
occurs:

:WARN:  /nutchwax/opensearch:

Before this it has found 14 hits of the searched word:

2006-08-27 17:11:30,038 INFO  NutchBean - found 14 raw hits
2006-08-27 17:11:30,039 INFO  NutchBean - total hits: 1829

So the problem does not seem to be searching in the indeces. Maybe there 
might be a problem with accessing the arcs to get the specific page. I put 
the correct path (searcher.dir) inside the nutch-site.xml and 
hadoop-site.xml

Has anyone any idea about how to solve this problem?
