Using Logback
Here are some details for implementing logback (http://logback.qos.ch/). As you may know, Logback is from the same author as Log4j. It has several enhancements including Filters and Custom Appenders.
1. Get Solr 3.5 http://www.apache.org/dyn/closer.cgi/lucene/solr/3.5.0 and extract the tar/zip file on your system.
Note: $ORIG is your top level directory for Solr.
# cd $ORIG
# tar xzvf apache-solr-3.5.0.tgz
2. Copy the solr.war file to a new location
# mkdir -p /tmp/solr
# cd ./example/webapps
# cp solr.war /tmp/solr
# cd /tmp/solr
# jar xvf solr.war
# rm -f solr.war
3. Remove the slf4j-jdk14-1.6.1.jar file
# cd /tmp/solr
# rm -f ./WEB-INF/lib/slf4j-jdk14-1.6.1.jar
4. Copy logback classic files
Get the file: http://logback.qos.ch/dist/logback-1.0.1.tar.gz
# tar xzvf logback-1.0.1.tar.gz
# cd logback-1.0.1
# cp logback-classic-1.0.1.jar /tmp/solr/WEB-INF/lib
# cp logback-core-1.0.1.jar /tmp/solr/WEB-INF/lib
Note: If you wanted to upgrade SLF4J from 1.6.1 to 1.6.4 you would do the following...
a. Get the SLF4J from http://www.slf4j.org/dist/slf4j-1.6.4.tar.gz
b. Extract the tar into a temporary directory
c. delete the old versions:
# rm /tmp/solr/WEB-INF/lib/jcl-over-slf4j-1.6.1.jar
# rm /tmp/solr/WEB-INF/lib/log4j-over-slf4j-1.6.1.jar
# rm /tmp/solr/WEB-INF/lib/slf4j-api-1.6.1.jar
d. Copy the new ones
# cp jcl-over-slf4j-1.6.4.jar /tmp/solr/WEB-INF/lib
# cp log4j-over-slf4j-1.6.4.jar /tmp/solr/WEB-INF/lib
# cp slf4j-api-1.6.4.jar /tmp/solr/WEB-INF/lib
5. Rebuild the war
# cd /tmp/solr
# jar cvf solr.war *
6. Copy the war back to your example/webapps directory
# cp solr.war $ORIG/apache-solr-3.5.0/example/webapps
7. Create resources/logback.xml file
# cd $ORIG/apache-solr-3.5.0/example
# mkdir resources
copy logback.xml into this directory.
8. Restart Solr 3.5
Example logback.xml.
