Hello.
I've been trying the webapp/logging examples on the wiki (http://www.jboss.org/wiki/Wiki.jsp?page=Logging) and have been running into problems/unexpected results.

Questions:
These questions refer to the steps outlined below.
Q1) In step B3 why is there no log file?
Q2) What do the error in step C2 mean? Is there a problem with the log4j.properties?
Q3) What extra logging info would be appropriate here? web/logging/everything?
Q4) General question: Has anyone seen a scenario where a deployed application disables all of jboss logging (console and server.log)?

Here are the steps i worked through:

-source: http://www.jboss.org/wiki/attach?page=Logging%2Flog4j.war.zip
-jdk: Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_03-b02)
-os: windows 2000
-jboss: clean installs of 3.2.3 and 3.2.5

A - JBoss example on 3.2.3

4. shutdown and remove deploy/log4j.war

B - JBoss example on 3.2.5
1. Deploy

4. shutdown and remove deploy/log4j.war


I then tried a modified version of the JBoss example.

JBoss example modifications
-renamed conf/log4j.xml to conf/jbosslog4j.xml
-edit 'ConfigurationURL' value in conf/jboss-service.xml to resource:jbosslog4j.xml
-in example webapp (log4j.war) replace classes/log4j.xml with classes log4j.properties

 log4j.debug=true
 log4j.rootLogger=FILE

 # A time/date based rolling appender
 log4j.appender.FILE=org.apache.log4j.FileAppender
 log4j.appender.FILE.File=${jboss.server.home.dir}/log/log4j-test2.log
 log4j.appender.FILE.append=false
 log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
 log4j.appender.FILE.layout.ConversionPattern = %d %-5p [%c] %m%n
