Hi all,
In a project we want to use log4j.
With the base configuration it works fine, no matter of how many
appenders we define:
log4j.rootCategory=error, D, S
log4j.appender.D=org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.DatePattern='.'yyyy-MM-dd
log4j.appender.D.File=base.#.log
log4j.appender.D.layout=org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
log4j.appender.S=org.apache.log4j.net.SyslogAppender
log4j.appender.S.SyslogHost=localhost
log4j.appender.S.Facility=user
log4j.appender.S.layout=org.apache.log4j.PatternLayout
log4j.appender.S.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
But we would like to separate the logging process.
Ex:
1. all messages comming from JSP pages to go to a JSP category,
wich contains a daily rolling appender and a syslog appender
(with a JSP facility),
2. all messages comming from JSP tags to go to a JSP_TAG category,
wich contains a daily rolling appender and a syslog appender
(with a JSP_TAG facility),
3. all messages comming from JDBC classes to go to a JDBC category,
wich contains a daily rolling appender and a syslog appender
(with a JDBC facility)
So, we need three categories, as follows:
log4j.rootCategory.JSP=error, D, S # for messages comming from
JSP pages
log4j.rootCategory.JSP_TAGS=debug, D, S # for messages comming from
JSP tags
log4j.rootCategory.JDBC=debug, D, S # for messages comming from
JDBC classes
# ----------------------------------------
log4j.appender.D=org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.DatePattern='.'yyyy-MM-dd
log4j.appender.D.File=grafl.#.log
log4j.appender.D.layout=org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=/oracle/log4j_syslog/x.log
log4j.appender.R.MaxFileSize=10MB
log4j.appender.R.MaxBackupIndex=2
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
etc.
How should we write the log4j.properties and use the appenders?
Thank you in advance,
