System.out is not going to catalina.out
I'm new to using tomcat. I've done some developing with Google App Engine,
but I'm looking to
host something on my own system instead of theirs.
My system is running Ubuntu 10.04.3. Tomcat is 6.0.24, JVM is 1.6.0_20-b20.
I've written my app using GWT 2.4.0. I'm also trying to use Hibernate and
MySQL for the back end.
This is my first time with Hibernate as well, so I'm still coming up to
speed with getting that configured
and working.
I can run my application in dev mode under Eclipse, with Hibernate
configured to connect to the mysql
server, and it works fine. But when host the application under Tomcat on
the server it doesn't actually
update the database. It seems to work, I get no errors or stack traces, but
the data never gets updated.
That leads to the real question I'm asking for help with - I can't seem to
get any kind of logging to work,
including simply writing to System.out. All the documentation I can find
says that System.out should get
written to catalina.out, but I'm not seeing it. I do see "deploying" and
"undeploying" messages in
catalina.out, so I know I've got the right file and it is getting logged to,
but I don't see anything else there.
I've tried changing logging.properties to specify level=ALL for everything,
thinking maybe the output was
getting filtered, but that didn't help.
Can anyone suggest what I might be doing wrong? Is my System.out going
somewhere else?
I'm generally pretty good at working out problems for myself, but with no
error messages and no way to
get any kind of logging I'm stuck. If someone could help me at least get
logging working I can probably
work the rest out.
Thanks,
Chris

Start with a clean Tomcat 7.0.23 install and a simple JSP that writes to
stdout.
Also, check all the other log files.

You really shouldn't be using System.out for logging; you webapp should include a logging framework of your choosing.
However, if you insist, enable the swallowOuput attribute in your webapp's <Context> element.

Thanks to everyone that offered suggestions. I upgraded to Tomcat 7. I
tried various logging options, and all kinds of changes to
logging.properties. I tried changing the way the Tomcat daemon is started.
I tried running Tomcat in the foreground instead of as a daemon.
In the end it turned out to be a stupid mistake, as I suspected it would be.
The problem was in the ant script that was building my WAR. It was picking
up an old jar instead of the latest files, so I essentially wasn't changing
anything when I made changes and redeployed.
All is working now. I've got logging working through slf4j, Hibernate is
persisting objects, and everything is good.

I will make another guess for now :
As your Tomcat is running under an Ubuntu, have a look at the script which starts Tomcat
(probably /etc/init.d/tomcat6). Tomcat probably runs under jsvc, and its stdout/stderr is
redirected (also guessing) to /var/log/daemon.log or similar.

Just guessing:
a) you are not using the configuration that you are think that you are using
b) you do not have enough rights or disk space to write to catalina.out file
You apparently are using 3-rd party repackaged and outdated
distribution of Tomcat. I'd be better to download proper 6.0.33 from
tomcat.apache.org and install it.
