org.slf4j.LoggerFactory error with Solr 4.3

[Eoghan Ó Carragáin]

Hi,

I've been having difficulty getting the SolrMarc 2.5.2 to work with Solr 4.3. Everything works fine with the HTTP/Remote mode, but when I try to run in the standard ("embedded"?) SolrMarc mode, I get "java.lang.ClassNotFoundException: org.slf4j.LoggerFactory" (see full error below).

The Solr wiki provides information on some changes that were made to the default logging in Solr 4.3+: http://wiki.apache.org/solr/SolrLogging#Solr_4.3_and_above.

I tried following the instructions under "Switching from Log4J logging back to Java-util logging" but it didn't appear to make any difference to SolrMarc.

Any ideas? Thanks!

Eoghan

Eoghan,

Were you able to solve this?  I just wrestled with Solr 4.3 and my version of SolrMarc and have gotten past this point.   Basically, it seems Solr 4.3 may expect servlet api 3.0 ;  I upgraded the Jetty in my solrmarc to 8.1.8  (was at 6).   There was a certain amount of mucking about with jar files and logging properties files, including using log4j in jetty for solr logging as well as using it for solrmarc logging.

Now I'm working on this error:

  org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Invalid UTF-8 middle byte 0xe0

which I think is related to the previous discussions on binary data and SolrJ for Solr 4, but am not sure yet.

Hi Naomi,
I'm afraid I haven't looked at it since. I was using jetty 8.1.8 & log4j logging for solr, but may have stumbled on getting solrmarc to use log4j. Thanks
