[OT] ServletExceptions in StartupServlet & Logging

[Matt Raible <ma...@raibledesigns.com>]

Is it possible with Log4j or other logging mechanisms to show
ServletExceptions in the console.  They show up fine in my tomcat
logfile, but not in the stdout.  

In tomcat's log file I get:

2002-02-22 10:09:52 StandardContext[/onpoint]: Servlet /onpoint threw

And I wan this to show up in either my application log or stdout so
System Administrators can see it - is this possible?

Here is my log4j.properties file:

log4j.rootCategory=info, stdout, R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%p [%t] [%c] %C{1}.%M(%L)
| %m%n

log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=onpoint.log

log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R.MaxBackupIndex=1

log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
