redirecting the output to a log file
Hi All,
I am using catalina. When my servlets are sending some stack trace / debug
output, all such output is dumped in the catalina window. I tried changing
the logger class in server.xml, used startup 2>output.txt etc but no
technique is working,
I am using standalone catalina on windows NT
Please suggest
Satya

Hello Satya,
These messages are in catalina.out
You can use tail -f catalina.out to see what is happening.
Or if you work on windows, you should go to the properties of the dosbox
and put the buffer size to 1000 lines than you can scroll up.
good luck,
Richard

Hi Richards,
I am already using file stream to write a log of my application specific
info (and will move the application in next iteration to
log4j).
However i am having problem with capturing the error messages which catalina
dumps if there is any error. They are appearing in the window in which
catalina
is running - since the scroll up immediatly, i could not read them, and they
are not
appearing in any of the log files under CATALINA_HOME\logs\
When i issued the bin\startup.bat >a.out or bin\startup.bat 2>a.err
it only prints that "tomcat started" etc but not
the error dump.
Regards
Satya

Hello Satya,
I suggest Log4j.
You can log to different out streams. You can configure the way you log
outside you program code, using a log4j.properties file.
@see http://jakarta.apache.org/log4j
Also you can use the catalina way of logging.
And you can make your own logging mechanism by appending to a
java.io.RandomAccess file. But keep in mind that you have to programm a lot
to make it thread safe etc.
Good luck.
Richard
