Re: [S2] Logging Issues

[Kelly Graus]

Hi Laurie,

Thanks for the reply!  I found the "swallowOutput" attribute in the 
Tomcat context that caused the exceptions to be placed in my application 
log. However, I'm now setting up global exception mapping in struts so I 
can handle unexpected problems without showing the user a stack trace.  
Making no changes other than adding a single global exception mapping 
for java.lang.Exception allows me to display a better error page to the 
user, but from reading the documentation I would have though that this 
would break my logging, since I didn't set the logEnabled property on 
the exception interceptor to true.  However, all logging seems to work 
correctly.  Do you know why this is?

Thanks!

You can't have log4j route exception errors to the log file if you 
don't catch the exception and pass it to log4j... If you allow the 
exception to propagate all the way up, it will be logged by the 
container. Short story: if you want to control where something gets 
logged to, you need to control how it is logged.

Hello,

I am writing an application using Struts (2.0.11), Spring (2.5.1), and
Hibernate (3.2.6), running on Tomcat (6.0.13).  We have a legacy webapp
running on Tomcat that outputs some important information to the default
Tomcat logs.  We aren't really in a position to change that 
application, so
we're trying to update our new webapp to put all messages in a 
different log
file.  I'm trying to do this using log4j (1.2.15).

So far, I can add messages to the new log in my java code.  I am also
getting freemarker.cache debug messages in the new log.  However, all 
other
messages are still being put in the default Tomcat logs.  For 
example, if
the database I'm trying to access closes its connection and I don't 
catch
the exception that is thrown, it gets printed to the screen, and put 
in the
catalina log.  I would like that exception to go in the new log file 
instead
(and yes, eventually I will catch the exception and have struts 
display a
nicer error message for the user).

Below are the relevant parts of my web.xml, and my log4j.properties 
file. Any help would be greatly appreciated!

Thanks!

Kelly
