tomcat and log4j, again
OK, with my current configuration, I *am* seeing
output in catalina.out. However, its not formatted
the way I (think I) told it to. Also, I would
prefer to have the output go to a separate log
file, as there is just too much stuff in catalina.out
to wade through.
Anyway, I am using RH9, jakarta-tomcat-4.1.24,
and log4j-1.2.8. For my webapp, I am
creating a war file that has log4j.properties
in the WEB-INF/classes directory. I dropped
log4j-1.2.8.jar into the WEB-INF/lib directory.
The log4j.properties file looks like this:
log4j.logger.fermataintl.migrasponder=DEBUG, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d [%t] %-5p %F:%L - %m%n
=================================================================
I am not explicitly initializing log4j. A class that I am using
in my app invokes logging as follows:
package fermataintl.migrasponder.common;
import java.sql.*;
import org.apache.log4j.*;
public class Vendor
{
...
logger.warn("attempt to authenticate '" + id + "' failed");
...
private static Logger logger = Logger.getLogger(Vendor.class);
}
==================================================================
When I run my app and exercise the bit of code containing the
warning above, it puts the following in catalina.out:
1571947 [Thread-5] WARN common.Vendor - attempt to authenticate 'xxx'
failed
===================================================================
So... my questions are:
1) How do I get output to a file of my own choosing
2) How do I get the formatting to come out with date and time prepended?
Thanks.

PS. I looked for the commercial manual (on the website) at 2 local
bookstores and on amazon.com. Nobody has it. I hesitate to order from
Switzerland, as I am in the US. How long would that take...

PS. WRAX press' Tomcat book has a section on Log4J. Pretty simple, 20 pages
tops, but it will get you started. If you can get a handle of that, of course.

You can "The complete log4j manual" in the US from Softpro books:
http://store.yahoo.com/softpro/2-9700369-0-8.html
They should have it in stock.
Otherwise, your hesitation about purchasing the book from Switzerland
is quite normal. Of course, much of the log4j code was written in
Switzerland as anyone can guess from the cheesy smell of the code.
People in Switzerland are notorious for their feet and the cheesy
smell they exude. Some say that it is the Swiss feet that give the
cheese its uniquely rich aroma and flavor, or maybe it is the other
way around...
Interestingly enough, while visiting the US on vacation, a waitress
asked us what kind of cheese we wanted in our sandwich. She listed
the various sorts and we stopped her as soon as she pronounced the words
"Swiss cheese". We enthusiastically repeated "Swiss cheese" with a
twinkle in our eyes, yearning for the Gruyere or possibly the Vacherin
fribourgeois that we enjoy so much. Talk about a cultural shock when
we realized that "Swiss cheese" in the US means a gooey slice of
plastic with holes in it. To be fair, it loosely resembled the
Emmental but that is probably stretching the word "loosely."
Anyway, we loved every minute of our visit, although there were a few
rare exceptions which are better kept unshared.
If you are wondering if I've lost a marble or two during my stay in
London, I've been sick since my return. And the Apache rules
specifically state** everyone is allowed to go on a tangent once in a
decade. It's my turn. :-)
** If you don't believe me, read the ASF bylaws. It's around section
43 or thereabouts.

1. look into using fileappenders, or even better rolling file appenders.
2. in the log4j api find patternlayout. it has very good documentation.
d Used to output the date of the logging event. The date conversion
specifier may be followed by a date format specifier enclosed between
braces. For example, %d{HH:mm:ss,SSS} or %d{dd MMM yyyy HH:mm:ss,SSS}. If
no date format specifier is given then ISO8601 format is assumed.
The date format specifier admits the same syntax as the time pattern string
of the
<http://java.sun.com/products/jdk/1.3/docs/api/java/text/SimpleDateFormat.html>SimpleDateFormat.
Although part of the standard JDK, the performance of SimpleDateFormat is
quite poor.
For better results it is recommended to use the log4j date formatters.
These can be specified using one of the strings "ABSOLUTE", "DATE" and
"ISO8601" for specifying
<../../../org/apache/log4j/helpers/AbsoluteTimeDateFormat.htm>AbsoluteTimeDateFormat,
<../../../org/apache/log4j/helpers/DateTimeDateFormat.htm>DateTimeDateFormat
and respectively
<../../../org/apache/log4j/helpers/ISO8601DateFormat.htm>ISO8601DateFormat.
For example, %d{ISO8601} or %d{ABSOLUTE}.
These dedicated date formatters perform significantly better than
<http://java.sun.com/products/jdk/1.3/docs/api/java/text/SimpleDateFormat.html>SimpleDateFormat.
Hope this helps
