Hi,
I am trying to use the FallBackErrorHandler but cannot seem to get it to work. Here is
my log4j-config.xml file:
<appender name="systemmonitor" class="org.apache.log4j.FileAppender">
<errorHandler class="org.apache.log4j.varia.FallbackErrorHandler">
<root-ref/>
<appender-ref ref="fallback" />
</errorHandler>
<param name="File" value="c:/temp/logs/system_monitor.log"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%r [%t] %-5p %c{2} %x - %m%n"/>
</layout>
</appender>
<appender name="fallback" class="org.apache.log4j.FileAppender">
<param name="File" value="c:/temp/logs/fallback.log" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%r [%t] %-5p %c{2} %x - %m%n"/>
</layout>
</appender>
<category name="SM" additivity="false">
<priority value="DEBUG"/>
<appender-ref ref="systemmonitor"/>
</category>
<root>
<priority value="DEBUG"/>
</root>
I changed the access level of the primary appender's file so that it cannot be written
to. When I start up my project in eclipse, I see the following go by:
log4j: Setting property [file] to [c:/temp/logs/system_monitor.log].
log4j: Parsing layout of class: "org.apache.log4j.PatternLayout"
log4j: Setting property [conversionPattern] to [%r [%t] %-5p %c{2} %x - %m%n].
log4j: setFile called: c:/temp/logs/system_monitor.log, true
log4j: FB: The following error reported: setFile(null,true) call failed.

log4j: FB: INITIATING FALLBACK PROCEDURE.
log4j: FB: Searching for [systemmonitor] in logger [root].
log4j: FB: Replacing [systemmonitor] by [fallback] in logger [root].
log4j: FB: Adding appender [fallback] to logger root
log4j: Adding appender named [systemmonitor] to category [SM].
Which looks just fine. But nothing gets logged to the fallback log file. Can someone
point out what I am missing? Any help will be greatly appreciated.
Thanks!
