Hi Chris,
Christopher Schultz wrote on 17.12.2010 18:55:
I can see an stderr file in there. Were you expecting anything to be in
it immediately after startup? Silly question: how are you writing to stderr?
yes, I put some output in one of my servlets, just to test this.
I'm using System.stderr and System.stdout.
BTW: you posted some passwords in your log files. You might want to go
and change those, now, unless it was all some kind of test data.
yup, I know, it's only test data...
I was thinking of your conf/logging.properties file as well as your
configuration for tomcat6w.exe. Describing the log config from
tomcat6w.exe (as you have done) and posting logging.properties should be
enough.
see attachment
Logging set up from tomcat6w:
* Level: Info
* Log path: apache install dir\logs
* Log prefix: jakarta_service_
* Redirect Stdout: auto
* Redirect Stderr: auto
There is a swallowOutput attribute on theContext element (found in
conf/server.xml if you are a bad boy, or in your webapp's
META-INF/context.xml, or in conf/[service]/[host]/[webapp].xml. If set
to true (it defaults to false), then your stdout and stderr will be
redirected to the application's log file which is configured in
conf/logging.properties.
this attribute is not set anywhere.

Chris,

No wonder it's not working: System.stdout and System.stderr don't exist
as far as I know. Did you mean System.err and System.out? Precision
counts, especially when things aren't working the way you expect them to be.
you are right. Of course I use System.err and System.out
I was thinking of your conf/logging.properties file as well as your
configuration for tomcat6w.exe. Describing the log config from
tomcat6w.exe (as you have done) and posting logging.properties should be
enough.

my last attachment went through even so I go an error message. This time
I didn't get a message so I would have thought it's ok.
I now put it at the end of the message.
Logging set up from tomcat6w:
* Level: Info
* Log path:apache install dir\logs
* Log prefix: jakarta_service_
* Redirect Stdout: auto
* Redirect Stderr: auto
Someone more familiar with win32 will have to comment on what those
settings are expected to produce. Note that the Log* parameters have
nothing to do with stdout/stderr: they are for reporting (whatever) to
the Windows System Log.
The documentation I can find for the --StdOutput and --StdError
command-line parameters seem to indicate that they describe a filename.
I would expect auto to be the filename. If you haven't specified the
path, you will have to check the working directory of the service to
determine where that file will try to be written.
I'm not sure if Tomcat's service wrapper will fail silently or angrily
if files cannot be created. If I were you, I'd specify an exact
filename, including full path, for the Redirect Stdout and Redirect
Stderr settings, and make sure that the effective user running the
Tomcat service (TOMCAT? LOCAL_SERVICE?) has rights to write to that
file/directory.
this is exactly what I did on a previous suggestion. I replaced the
auto bits with C:\tmp\stderr and C:\tmp\stdout. Tomcat creates the
files and writes into stdout. It also creates stderr but it remains
empty. When I set it to auto the files are created in the standard log
directory with the names stdout_XXX.log and stderr_XXX.log where XXX is
the date the files were created.
So from this behaviour I would say, that these settings are for output
of Tomcat (too).
