Subject Re: Problem with Solr logging under Jetty
Date Thu, 19 Jul 2012 16:28:54 GMT
Hello,

I have a similar problem, anything new about this issue?

My problem is that info logs go to stderr and not stdout, do you have an
explanation?

For the log level I use the file "logging.properties" with in it only one
line setting the level.

============================================
.level = INFO
============================================

and I have a configuration file called "jetty-logging.xml" passed at
startup of jetty through start.ini for redirect stdout to a file and stderr
to another file, the config looks like this:

============================================
<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "
http://www.eclipse.org/jetty/configure.dtd">


<Configure id="Server" class="org.eclipse.jetty.server.Server">
