Thanks Andre!
But when tomcat5 starts, it will generate a file like stdout_yyyymmdd.log,
but when it runs for a couple of days, there will be only one file, and all
the infos are appended to that file. What I want is that tomcat can
automatic generate multiple files such as one file one day so that the
single log file will not be so large.
Like in log4j, I can set the parameter like
"log4j.appender.R=org.apache.log4j.DailyRollingFileAppender" so that
everyday it will generate a new file.
in the "logging" tab page, I can only redirect the stdout to a single file.
Does it support parameters like "D:\Tomcat 5.5\logs\{%date%}.log"?
I don't know, and I did not find anything to that effect in the Tomcat or Daemon
documentation.
But you could try the following :
In the Apache httpd distribution, there is a program called "rotatelogs.exe".
Its documentation is here :
http://httpd.apache.org/docs/2.2/programs/rotatelogs.html
You could try to download Apache, extract this program, add it to the tomcat/bin
directory, and then in tomcat5w.exe try to set the filename to something like :
|D:/Tomcat 5.5/bin/rotatelogs.exe -l D:/Tomcat 5.5/logs/stdout.%Y.%m.%d 86400
I have never tried this, and I don't know if it works.
If it does, then let us know, because it might be handy for others.
Note : I know that this is not the default in the Tomcat installation, but I always
recommend to install programs in directory paths *without embedded spaces* (e.g.
"D:/tomcat5.5" instead of "D:/tomcat 5.5". One of the reasons is shown above : does one
need to quote this path or not, and if yes how ?

Hello everyone,
I am using Tomcat 5.5.28 in Windows systems. Because there are lots of
codes
like "System.out.println(" some info here")" in the apps, after a few days
the file "stdout_*.log" in the "/logs" folder becomes so large that we
cannot open it. Due to some reasons, I cannot modify the codes, so the
only
solution is to make the log generated everyday.
I have tried the log4j, but I cannot redirect the stand output to the log
files. Only there log infos that send out by logging class can be recorded
in the logs generated by log4j.
Anyone know a simple solution to meet my needs?
Hi.
You do not say, but I presume that you are running Tomcat 5.5 as a Windows
Service.
If so, then Tomcat (or rather the JVM which runs Tomcat), is running inside
of a "wrapper" program called "tomcat5.exe" (tomcat_dir/bin/tomcat5.exe).
This program "catches" the stdout/stderr of the JVM, and redirects them to
files.
To which files it redirects them, is stored in the Windows Registry.
When tomcat5.exe starts, it reads a series of parameters from the Registry,
and then starts the JVM (and Tomcat) using these parameters.
There is another program in tomcat_dir/bin, called "tomcat5w.exe".
This is a GUI which enables you to change these Registry parameters used by
tomcat5.exe.
Double-click on the tomcat5w.exe program, and navigate to the "Logging"
tab.
Maybe this gives you an idea.
For a complete explanation, start here : http://commons.apache.org/daemon/
tomcat5.exe is really a renamed prunsrv
tomcat5w.exe is really a renamed prunmgr
