Tomcat 6 Log Tomcat output to file

I usually install Tomcat as a Service under windows which causes all
Tomcat output to go to stdout.log.  I am in a situation where I can
not do this.  I have to start Tomcat from the command line.  When I do
all of Tomcats output is logged to the console.  How do I manually
configure Tomcat so the output gets logged to a file?

I tried the instructions under the log4j section here
http://tomcat.apache.org/tomcat-6.0-doc/logging.html

When I restarted Tomcat no new log file was created.  The output
stilled logged to the console window.

I couldn't find any other documentation on how to do this in Tomcat 6.

Can some one point me to some documentation on how to set up this type
of logging?

Thank you

Indeed; thanks for the correction.

Scratch that - it's not complete; it should be:

catalina.bat > outputfile.log 2>&1

Most of the log messages are sent to stderr, not stdout, so the two redirections are needed.

You will need to run shutdown.bat from a separate command prompt, or use CTRL-C in the original one, along with answering y to the now-hidden terminate message.

the > logfile still only logs the Using messages that I posted earlier.

I tried adding > outTest.txt at the bottom of Catalina.bat after each
of the commands that start tomcat.  The output is still logging to the
console window.  I tried removing the 'start' prefix from %_EXECJAVA%.
 In DOS start is what launches a new cmd window.  This caused an
error.

I'll keep trying different things.  If anyone has any more suggestions
they would greatly appreciated.

I might move back to the original documentation and see if I can just
get the loggers set up properly.

Thanks

It requires a bit of work examining the startup.bat and catalina.bat 
files, but maybe try this :

startup.bat run > logfile

If I interpret these bat files correctly, that should start Tomcat in 
the same window. (To stop it, just type CTRL-C).
If not, then you are welcome to go look for yourself.

No this only writes the following:

Using CATALINA_BASE:   D:\liferay\tomcat-6.0.18
Using CATALINA_HOME:   D:\liferay\tomcat-6.0.18
Using CATALINA_TMPDIR: D:\liferay\tomcat-6.0.18\temp
Using JRE_HOME:        D:\liferay\tomcat-6.0.18/jre1.5.0_17/win

Then it spawns a new window for Tomcat output.

Could you specify what you did do? Posting your logging.properties file
would also be helpful.

I believe there are a few messages that Tomcat simply logs to
System.out/System.err and there's nothing you can do about that.

STARTUP.BAT calls CATALINA.BAT which, as you have seen, runs "START
java.exe ...". If you read through that mess, you'll see that no output
redirection is done. I think Windows doesn't do stdout/stderr
inheritance when one process calls another (or, at least, running
"start" escapes that). Finally, the "start" command doesn't appear to
have a "redirect stdout to a file" option.

It looks like you already tried redirecting the output of "start" to no
avail.... looks like Windows is fighting you, here.

Is Tomcat itself generating a lot of output? If you have your logging
configuration correct, very little should end up on stdout. If it's your
webapp that's spewing to stdout, check out the "swallowOutput" attribute
of the <Context> configuration element in context.xml. You'll still have
to have a sane logging configuration for this to work properly.
