Hello,
I have an issue with the initialization of log4j with a xml file. log4j is
not seeing the custom appender I have made.
I have try to put the log4j.jar in
$CATALINA_HOME/common/lib
and in $CATALINA_HOME/lib
with MyPackage.MyAppender in
webApp/WEB-INF/classes/MyPackage/MyAppender.class
I have the following error :
log4j:ERROR Could not create an Appender. Reported error follows.
java.lang.ClassNotFoundException: MyPackage.MyAppender

at org.apache.log4j.xml.DOMConfigurator.configure(DOMConfigurator.java:606)
If I put the log4j.jar in webApp/WEB-INF/lib everything is working fine. It
looks like it is an issue with the classloader, but looking at :
http://jakarta.apache.org/log4j/docs/TROUBLESHOOT.html
I don't see what I am doing wrong,
Any help would be appreciate. Thanks in advance,
Marie
