Hello,
I am very new to both Tomcat4 and Log4J. I have been using apache-jserv
for a very long time and finally decided to jump into Tomcat. I found
tomcat doing the System.err logging to catalina.out file in
/vat/tomcat4/logs directory. I would like to leave whatever tomcat4 does
as it is. In addition to that I would like to use Log4J to log debug,
info, warning messages that are specific to different context. I have
gone through this mailing list's archeive and couldn't find any
reference to similar question. So, I am posting it.
Here is what I have done
in /etc/tomcat4/conf/tomcat4.conf file I added this
export CATALINA_OPTS="-Dlog4j.configuration=log4j.properties"
I have placed the log4j-core.jar, parser.jar, jaxp.jar files in
/var/tomcat4/webapps/myapp/WEB-INF/lib/ directory
I have the file log4j.properties in
/var/tomcat4/webapps/myapp/WEB-INF/classes/ directory. Follwing is the
content of that file
log4j.rootCategory=DEBUG, A1
log4j.appender.A1=org.apache.log4j.FileAppender
log4j.appender.A1.File={CATALINA_HOME}/logs/myapp.log
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r %-5p [%t] (%x) - %m\n
In my servlet I have the follwoing lines
import org.apache.log4j.*;
....
...
PropertyConfigurator.configure("/var/tomcat4/webapps/eis/WEB-INF/classes/log4j.properties");
PropertyConfigurator.configureAndWatch("/var/tomcat4/webapps/eis/WEB-INF/classes/log4j.properties");
// Initialize a logging category. Here, we get
THE ROOT CATEGORY
//static Category cat = Category.getRoot();
// Or, get a custom category
cat = Category.getRoot();
cat.setPriority(Priority.DEBUG);
// From here on, log away! Methods are:
cat.debug(your_message_string),
// cat.info(...), cat.warn(...), cat.error(...),
cat.fatal(...)
cat.debug("Testing the logger DEBUG");
cat.info("Testing the logger INFO");
cat.warn("Testing the logger WARN");
cat.error("Testing the logger ERROR");
cat.fatal("Testing the logger FATAL");
I am basically using tomcat4 as servlet container. myapp is my context.
The servlet part of it working just fine. I does rest of the things that
I have, except the log4j part. I have the tomcat4 threads that looks
like this
tomcat4 30939 30938 0 16:26 ? 00:00:02

/usr/java/j2sdk1.4.0/bin/java -Dlog4j.configuration=log4j.properties
-Djava.endorsed.dirs= -cl
I would greatly appreciate if you folks can help me out in configuring
this correctly. I wish the log4j documentation had more information on
installation of configuration with tomcat.
Thanks
