I've tried pointing : 'java.util.logging.config.file' to a properties file, as well as specifying how have you tried pointing it at a properties file? it's a system property that needs to be set before tany code attempts to load any of the logging related classes, so in JRuby you may have to do soemthing special to specify it before JRUby loads the JVM (normally it can only be set on the command line when executing java, System.setProperty doesn't work (in any JVM) worst case scenerio, you can modify the default logging.properties file that is in the JVM JRuby runs. : What I'd like to do is programmatically direct the Solr logs to a logfile, : so that I can have my app start up, parse its config, and throw the Solr : logs where they need to go based on that. : : So, I don't suppose anybody has a code snippet (in Java) that sets up SLF4J : for Solr logging (and that doesn't reference an external properties file)? SLF4J is just a proxy API, it doesn't know anything baout log files or log levels or log filtering ... you can programaticly change the JUL Logging using the LogManager API... http://java.sun.com/j2se/1.4.2/docs/api/java/util/logging/LogManager.html http://java.sun.com/j2se/1.4.2/docs/api/java/util/logging/LogManager.html#getLogger(java.lang.String) http://java.sun.com/j2se/1.4.2/docs/api/java/util/logging/Logger.html#addHandler(java.util.logging.Handler) http://java.sun.com/j2se/1.4.2/docs/api/java/util/logging/FileHandler.html -Hoss
Re: Programmatically configuring SLF4J for Solr 1.4?
2009/11/1 Ryan McKinley ryan...@gmail.com I'm sure it is possible to configure JDK logging (java.util.loging) programatically... but I have never had much luck with it. It is very easy to configure log4j programatically, and this works great with solr. Don't suppose I could trouble you for an example? I'm not terribly familiar with Java logging frameworks just yet.
Programmatically configuring SLF4J for Solr 1.4?
So, I've spent a bit of the day banging my head against this, and can't get it sorted. I'm using a DirectSolrConnection embedded in a JRuby application, and everything works great, except I can't seem to get it to do anything except log to the console. I've tried pointing 'java.util.logging.config.file' to a properties file, as well as specifying a logfile as part of the constructor for DirectSolrConnection, but so far, nothing has really worked. What I'd like to do is programmatically direct the Solr logs to a logfile, so that I can have my app start up, parse its config, and throw the Solr logs where they need to go based on that. So, I don't suppose anybody has a code snippet (in Java) that sets up SLF4J for Solr logging (and that doesn't reference an external properties file)?

It is very easy to configure log4j programatically, and this works great with solr. To use log4j rather then JDK logging, simply add slf4j- log4j12-1.5.8.jar (from http://www.slf4j.org/download.html) to your classpath ryan On Nov 1, 2009, at 11:05 PM, Don Werve wrote: So, I've spent a bit of the day banging my head against this, and can't get it sorted.
