Thank you very much. That is exacly what I need.

You could map the 3 strings onto MDC key-value pairs, e.g. (m1, string1)
and address them in a PatternLayout by %X{m1}, etc.
Hope this is what you were looking for.

Dear All
Is it possible to log for example a object with 3 strings and
refer it
later in PatternLayout with e.g %m1 %m2 %m3 ?
Below there is some dummy code.
Thanks in advance for any hint.
Best Regards
Joerg
Example dummy code:
--
class MESSAGE{
public String a;
public String b;
public String c;
public message (String a, String b, String c)
{
this.a = a;
this.b = b;
this.c = c;
}
}
-
somewhere in the program
MESSAGE message new MESSAGE (hello, log, reader);
logger.getLogger(CategoryName).log(WRAPPER_FQN, Level.INFO,
message,null);
in the log4j.xml
appender ...
layout class=org.apache.log4j.PatternLayout
param name=ConversionPattern
value=%m1 %m2 %m3) /
/layout
As output from the appender
hello log reader

log4j for Tomcat and separate log4j config for each web app
I have seen info on how to use log4j for Tomcat and I have seen info on how to use log4j for a web app, but I haven't seen info on how to use log4j for Tomcat logging with a separate config for each app. I am having troubles getting that to work. Does anyone know of a web page that explains that? -- James Stauffer http://www.geocities.com/stauffer_james/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: log4j for Tomcat and separate log4j config for each web app
AFAIK there will be only one log4j configuration per Tomcat. If you want to differentiate logging behavior between your applications you either: - have a Logger per application OR - if you already have a Logger per class, you could make use of the hierarchy in log4j and change logging behavior on some intermediate node of this hierarchy (the 'root' of your application) I have seen info on how to use log4j for Tomcat and I have seen info on how to use log4j for a web app, but I haven't seen info on how to use log4j for Tomcat logging with a separate config for each app. I am having troubles getting that to work.

I am unable to get that to work. If there is no web site that explains how to do that then I can post what I have tried and what happened. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: log4j for Tomcat and separate log4j config for each web app
Hi James Did you try the following: 1. add log4j.jar to your application WEB-INF/lib 2. add log4j.xml to your WEB-INF/classes 3. connect from your application with e.g. private static Logger logger = null; logger.getLogger(CategoryName).log(CategoryName, Level.INFO, message,null); I remeber that log4j configures itself if the configuration file is in WEB-INF classes. May be some other person knows more about it. Best Regards Joerg James Stauffer wrote: I am unable to get that to work.

Re: log4j for Tomcat and separate log4j config for each web app
I have log4j.jar in WEB-INF/lib and common/lib (so Tomcat can use it). I have log4j.xml in WEB-INF/classes and common/classes. It appears that once it is configured once for Tomcat it won't do it for the app. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: log4j for Tomcat and separate log4j config for each web app
Quoting Ceki Gülcü [EMAIL PROTECTED]: James, Have a look at this document: http://www.qos.ch/logging/sc.jsp Following that, CVS check out log4j 1.3 and consult the examples located under ./examples/tiny-webapp/ Although the documentation in ./examples/tiny-webapp/ is up to date, certain important details in log4j 1.3 ContextJNDISelector have changed. I have not recently tested the code in ./examples/tiny-webapp/. Thus, it may contain some small errors. I think there is an error in the tiny-webapp docs because there is no more automatic configuration of non-default logger repositories in Log4j-1.3, which the tiny-webapp assumes. Please correct me if I'm wrong about this. Jake I hope this helps, At 03:33 PM 1/18/2005, James Stauffer wrote: I am unable to get that to work.
