Re: [POLL] How do you (like to) do logging with Solr
Hi, If you've setup your Tomcat with log4j logging, and want to add Solr, within the same logging config, you need to: #1. Remove slf4j-jdk14-1.6.1.jar from solr.war (unpack, remove, repack) #2. Download slf4j-log4j12-1.6.1.jar (from slf4j.org) and place it in e.g. tomcat/shared/lib If solr.war shipped without a pre-packaged binding, you could skip #1. The binding jar you deploy to appserver lib would also take effect for any other webapp using slf4j deployed to the same app-server. An alternative to manually repackage solr.war as in #1, is Hoss' suggestion in SOLR-2487 of a new ANT option to build Solr artifacts without the JUL binding. -- Jan Høydahl, search solution architect Cominvent AS - www.cominvent.com On 18. mai 2011, at 18.33, Shawn Heisey wrote: On 5/17/2011 10:00 AM, Chris Hostetter wrote: : If I understand what you've said above correctly, removing the binding in : solr.war would make it inherit the binding in jetty/tomcat/whatever, is that : right?

Re: [POLL] How do you (like to) do logging with Solr
I usually build solr using 'ant test dist' to run tests and build the .war and other jars, in particular the dataimporthandler. Having an alternate ant option to build without the binding would work for me. If/when I get around to changing logging mechanisms, I wouldn't be able to use the binary distribution, but with 3.1 I am already including selected patches from branch_3x and building it myself. I can see that there is a lot of resistance to just removing the binding entirely. I think that's a better option, but I know it's important to take care of the complete novices and their initial experience with the software. [ ] I always use the JDK logging as bundled in solr.war, that's perfect [ ] I sometimes use log4j or another framework and am happy with re-packaging solr.war [X] Give me solr.war WITHOUT an slf4j logger binding, so I can choose at deploy time [X] Let me choose whether to bundle a binding or not at build time, using an ANT option [ ] What's wrong with the solr/example Jetty?

Re: [POLL] How do you (like to) do logging with Solr
I'm not a Solr/Lucene programmer. I'm a guy who does web sites (using PHP!) who wants a good search engine. And the search *functionality* in Solr rocks - great job, guys!

Right - after reconsidering this, I want to retract my vote for removing the slf4j binding. It makes a lot of sense to have something that works out of the box, and after thinking about this I realized that the thing I was having to ignore was actually slf4j dependencies in the maven artifacts for solrj and solr-core, and not really related to solr.war at all. Anyway maven gives you tools for masking out these dependencies, so I really have no need for packaging changes in solr. -Mike

Re: [POLL] How do you (like to) do logging with Solr
We use log4j explicitly and find it irritating to deal with the built-in JDK logging default. We also have conflicts with other packages that have their own ideas about how to bind slf4j, so the less of this the better, IMO. The 1.6.1 no-op default behavior seems a bit unfortunate as out-of-the-box behavior to me though. Not sure if there's anything to be done about that.
