"By default, only java.util.logging is available for the core Tomcat" The key word there is "core". I'm assuming that you want to use log4j for your *application* logging, not to log internal Tomcat server activity. If so, you can safely ignore the references above as they do not apply to your situation. > I even found a website where a person stated that anybody using JCL with > tomcat are just plain stupid.

You are yet to demonstrate that there is a problem with Tomcat, or in fact the Tomcat is unable to use Log4J. As I stated before, I am successfully using JCL and Log4J on a number of servers - as I'm sure other lists members are too. > Also If I use the exact same lib files in the exact > same place and the same configuration file but I replace > protected final Log log = LogFactory.getLog( class ) (JCL) > with > protected final Logger logger = Logger.getLogger( class ) (Log4j) > > it should produce the same logging but it doesnt.

I am trying to, but you're determined to stick to your faulty assumption that there's a fault with Tomcat (which there doesn't appear to be to me). I shall repeat my questions: * have you set a logging level that will permit log messages to be written to the file? * what attributes are set in your application context configuration? E.g. is the swallowOutput="true" attribute set? http://tomcat.apache.org/tomcat-6.0-doc/config/context.html Answer these, and we'll continue. p > Thanks in advance, > Martyn > > > > Pid schreef: >> Martyn Hiemstra wrote: >> >>> Hi All, >>> >>> I have been working with tomcat and log4j for a while and it worked >>> perfectly.
