After a bit of testing I got it working. Basically all the configuration for log4j by default is under server/resources/log4j.properites. By default log4j should be able to find log4j.xml if you delete log4j.properties. I tried it and that's no the case.
I figured out this is due the fact that solr script "solr start" sets the configuration file manually. I replaced in the script "log4j.properties" by "log4j.xml" and it works well. I basically need it because some extensions don't work without log4j.xml. Please correct me if what I am doing doesn't make sense.
