Subject RE: java.lang.NullPointerException while trying to crawl RSS feed to Solr

The 'connection working' from rss doesn't mean much.  But the 'connection working' from solr
means that lcf could talk to solr and do a ping.

In any case, you should never see an NPE from lcf, so I am going to look into this at earliest
opportunity.  It is possible that the NPE is masking some other error, but maybe it is just

Subject: java.lang.NullPointerException while trying to crawl RSS feed to Solr

I have setup a connector against a RSS-feed with output to a Solr server. The repository connection
and output connection report that the connection is ok.

When I run the job it seems to retrieve the RSS feed and process everything as it should,
the data does not seem to get indexed into Solr however.

If I look in the lcf log file I find the following:
Error tossed: null
                             at org.apache.lcf.agents.output.solr.HttpPoster$

I guess there’s an error when it tries to post the data to Solr, but I can’t figure out
what the problem is. If I look at the catalina log for the tomcat where Solr is run I can’t
find any errors or anything else.

Does anyone have any tips?
