SolrJ and initializing logger in solr 4.3?

2013-07-11 Thread Jonathan Rochkind 

I am using SolrJ in a Java (actually jruby) project, with Solr 4.3.

When I instantiate an HttpSolrServer, I get the dreaded:

log4j:WARN No appenders could be found for logger 
(org.apache.solr.client.solrj.impl.HttpClientUtil).

log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for 
more info.



Using SolrJ as an embedded library in my own software, what is the 
proper or 'best practice' way -- or failing that, just any way at all -- 
to initialize log4j under Solr 4.3?


I am not super familiar with Java or log4j; hopefully there is an easy 
way to do this?


(If someone has a way especially suited for jruby, even better; but just 
a standard Java answer would be great too.)


Thanks for any advice!

Hi Jonathan,

I think you just need some config on the classpath:
