confused about simple logging
Hello.
I'm a bit confused about simple logging on tomcat 5.0. I've read much of the
FAQ at http://jakarta.apache.org/tomcat/faq/logging.html#builtIn but that
doesn't seem to address what I'm looking for, which is just routine mundane
daily activity.
For instance, if I create and deploy a simple "Hello World" application that
contains only index.jsp, no servlets, no external classes and no JNDI
resources, where on earth will a "hit" be recorded when I navigate to
http://localhost/helloworld/index.jsp ? And where is the error recorded if I
mistype and navigate to http://localhost/helloworld/jndex.JSP ?
Do I have to build such logging into the application? Or does Catalina handle
that for me? And if so ... where on earth?
I'm using FreeBSD installed at /usr/local/jakarta-tomcat5.0
I see log information in /usr/local/jakarta-tomcat5.0/logs/stderr.log
and /usr/local/jakarta-tomcat5.0/logs/stdout.log but nothing that records a
"page hit."
Thanks,
lane

I just took the Valve entry from a Host in my server.xml, stuck it
inside a ROOT.xml file changing only the prefix attribute, restarted
the server and bingo -- a context-specific log file is being created.
There's really not much to it, as the example in the docs shows.
Maybe you should post your entire Context file.

Thanks, Steven.
I got the <valve> configured and working in server.xml and immediately set
about trying to make it work only in a specific context. I guess I just
can't leave well enough alone :)
You are correct that for my purposes it is alright to log such requests
"system" (engine || server) wide.
But the documentation at
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/context.html#Special+Features
seems to imply such an access log can be maintained per-context.
I've tried to configure it in
$CATALINA_HOME/conf/Catalina/localhost/helloworld.xml and in
$CATALINA_HOME/webapps/hellowworld/WEB-INF/web.xml but the <Valve> seems to
be ignored unless it is in $CATALINA_HOME/conf/server.xml
I'm set now, but if anybody has information on per-context access logging it'd
sure help me troubleshoot.

Nope, catalina.out in c:\tomcat\logs if I recall correctly.

Alias might do what you want with one reservation, you cannot have
www.mydomain.com/bob
www.yourdomain.com/bob
as different folders. These will be the same folder. So each /folder will
have to be unique even though the domain names are different.

GOOD IDEA! I'll do that! (When this is done, I should have no logging at
all.)

If you really reach your wits end making logging work and just want a blunt
instrument to detect one-off if your overloaded method is called, when not
do something else to signal its presence, such as add a line to it which
creates a file called "ive.been.called" in a certain directory. Gets you
past having to fix your log/stream problem. You won't find this logging
framework in the TC docs though ;)

Sorry can't help you there. I was where you are now a year or more ago,
"fancy logging frameworks - too much hassle to learn for the simple logs
that I want". But I soon realised that it was more work, and quite a bit
more ugly, trying to do your own thing. I'd say bite the bullet and embrace
the latest release and logging framework. There have been a few different
ones over recent versions, but the TC dev team are converging them nicely
now. It might seem a little over engineered for simple logging requirements
at first, but once you spend the time to make it work, you will get what you
want, and come to realise that the advanced features are really useful for
debugging in situations exactly like yours.
I'm using commons-logging very successfully, is very flexible and not hard
to learn.

RE: confused about simple logging
Posted by Jim Henderson <jg...@metafile.com>.
Well I am having lots of self doubt.
I am trying to install my own overloaded JDBCRealm, I have been getting
some Sybase jdescripter error. (My backend DB has an old means of encoding
passwords so I overloaded the getPassword method.) I don't know if my code
is getting called or is it not. I have System.out.... trace statements in
the constructor after the call to the super ctor as well as the getPassword
method. And, I see none of my trace in any of the Tomcat log files.
This is frustrating after 3 days.

RE: confused about simple logging
Posted by Steve Kirk <to...@web-startup.co.uk>.
Not sure, ut I think all the output streams are diverted to that file. It's
probably configurable. Don't know full detail to be honest. Best wasy is
try it and see.

RE: confused about simple logging

If I write to stdout where does that go?
System.stdout.println("Where does this get printed to?");
I assume C:/tomcat.../log/stdout?

Your confusion possibly arises because there are at least 2 types of logger
that you might mean, and 3 main choices for one of those at the moment,
although one of those 3 is deprecated and a second is probably becoming less
popular.
OK I'll take a quick stab and see if this gets you anywhere in the right
direction.
You mention two distinct types of logging. The 1st is the "hit" logging
which is very similar to what you would get from apache httpd. This simply
logs each incoming request. This is achieved by adding a <Valve> to your
%catalina_home%\conf\server.xml - you can embed it inside the <Host></Host>,
<Engine></Engine> or <Context></Context> tags, but for your purposes, just
shove it in the engine for now. It looks a bit like this:
<Engine blah blah>
<Valve
className="org.apache.catalina.valves.FastCommonAccessLogValve"
directory="logs" prefix="ao_access_log_" suffix=".log"
pattern="common" resolveHosts="false"/>
</Engine>
You can tweak the path, filename, and the pattern that defines each line -
see
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/valve.html
for details. Leave resolveHosts set "false" to speed up performance.
Not that my example above is from my own 5.5.9 server - ISTR 5.0 config
syntax is different - check the doc link above for the detail.
The 2nd part of your logging is where you write your own messages to a
logfile. I did that as follows:
java.util.logging.Logger logger =
java.util.logging.Logger.getLogger("logname");
logger.setLevel(logLevel);
fh = new FileHandler(logFilePath, maxLogFileSize, logFileCount, true);
fh.setFormatter(new AoLogFormatter(logFileDateTimePattern));
logger.addHandler(fh);
Then to write a log message you can just do this:
log("Write this to the log");
and it will write the log file to logFilePath
See the java.util.logging.Logger javadocs for more details.
This is very basic. Much more spophistication can be achieved through
config files.
