hey,
I put this into C:\Program
Files\Apache\jakarta-tomcat-4.1.31\webapps\axis\WEB-INF\classes\log4j.properties
and deleted simplelog.properties from axis.jar. The bit that follows is the
logging code in my class I want to debug... but I don't see any logs in
C:\Program Files\Apache\jakarta-tomcat-4.1.31\logs, is there another
log4j.properties file that might overload this?
# Log4j configuration file.
# Set root logger level to DEBUG and its only appender to A.
log4j.rootCategory=DEBUG, A
# A is a DailyRollingFileAppender
log4j.appender.A=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A.file=C:\Program
Files\Apache\jakarta-tomcat-4.1.31\logs\wsAxis.log
log4j.appender.A.datePattern='.'yyyy-MM-dd
log4j.appender.A.append=true
log4j.appender.A.layout=org.apache.log4j.PatternLayout
log4j.appender.A.layout.ConversionPattern=%-5p %d{ISO8601} [%t] - %m%n
