I’ve got a web-app deployed to a Tomcat 7 server. My application uses log4j and a file appender. However, not all logging messages are getting written to the file.
On my classpath, I have:
log4j-1.2.14.jar
slf4j-api-1.6.1.jar
slf4j-log4j12-1.6.1.jar
My log4j.properties file is working fine on my local machine and is deploy properly.
I see application generated error messages being written to catalina.out that are not getting written to my log4j log. The log messages in catalina.out look to be coming from some other logging framework because the output pattern is in a different format than my log4j pattern. The logging that I’m seeing in the catalina.log is like:
Nov 4, 2011 11:05:31 AM org.apache.myfaces.shared_impl.util.StateUtils reconstruct
SEVERE
And my log4j pattern is like:
2011-11-03 16:42:09,336 ["http-bio-8080"-exec-13] ERROR
Some logging appears in my log4j file log, but not all of it. From what I’ve read, slf4j just needs those jars for it to funnel log output. Any ideas?
try including the jcl-over-slf4j as a dependency. myfaces is probably using commons-logging.
check the slf4j docs: http://www.slf4j.org/legacy.html#jcl-over-slf4j
