I have tried logging in my application two ways, on Tomcat 4.0.1, and have
had 2 problems that someone might be able to help me with ...
1) tried logging with the log taglib from Taglib project, with an error
that
log4j:ERROR No appenders could be found for category (root).
log4j:ERROR Please initialize the log4j system properly.
Here is the log4j.properties that I put in /WEB-INF/classes (and also tried
in /WEB-INF)
---
# Sample properties to initialise log4j
log4j.rootCategory=debug, stdout, R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=logtags.log
log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R.MaxBackupIndex=2
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

I placed the log.tld in /WEB-INF and log.jar in /WEB-INF/lib. Tried to use
the example logging .war that was in the taglib download, and although it
executes fine, I get no log files.
2) using the logger implementation in tomcat, I was successful logging
without a verbosity level, but when I use one, I got the following
following exception
2001-11-26 09:12:15 StandardWrapperValve[jsp]: Servlet.service() for
servlet jsp threw exception
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occured between lines: 16 and 25 in the jsp file:
