I have an old webapp that uses log4j 1.2 and which I am trying to deploy on tomcat. For the heck of it I can't get tomcat to use the log4.properties file. What am I doing wrong? tomcat 9.0.6 is installed as a Windows service and does serve my webapp, so the app is working fine. The project

RE: log4j: Logging to same file from multiple contexts?

Dear Dave, I walk through that years before, too. Yes - you can't let write different Log4J Appenders to the same file or you get this garbage. Yes - you have property resolving here, but there are no properties you need. We did a solution using an additional servlet called at application

log4j: Logging to same file from multiple contexts?

Dear Tomcat Users, Apologies if this is more of a log4j question, but I thought that I'd start here, in case Tomcat has any easy remedies. I have a common webapp that I deploy to multiple, different contexts. In log4j.properties, I have a few different log files defined, e.g., for logins

RE: log4j

Depends on what you're asking. If you're asking to use log4j to capture Tomcat logging, then the answer is - you can't but you can use Log4j2 or JULI. If the question is how to use log4j for your apps deployed under Tomcat, then answer can be found easily... From: Cheltenham, Chris

Re: log4j

Also, it may make more sense to code log4j into your app. If you change servers the logging goes with it. Best, J On Fri, May 18, 2018 at 8:06 AM M. Manna <manme...@gmail.com> wrote: > Hi Chris, > > How r u planning to use Log4j (or log4j2, which solves a lot of performance >

Re: log4j

Hi Chris, How r u planning to use Log4j (or log4j2, which solves a lot of performance issues for 1.2.x)? Are you bridging with SLF4J or or using directly? All log4j configuration are automatically discovered and configured provided that you have set up your appplication log4j properties file

Hello, How do I configure Tomcat 8.5.x to use log4j? Is there a good document to follow? I am not very familiar with java but it looks like you configure to logs to accept java logging for Tomcat. === Thank You; Chris Cheltenham Technology Services

Log4j Issue

I am using Log4j in my web app to write the logs to a separate file. Surprisingly, that log file is not at all getting created. I run the logger logic as a standalone application and the log file indeed gets created. I am assuming tomcat is not allowing me to write my logs to a file
