I extended AppenderSkeleton to create a custom appender called HTTPAppender, but something is up with the reference to it in the xml file. Log4Net is clearly unable to find my custom appender. Is there a way to reference it from the xml file to point to my project, or would I have to add my custom appender's source code to log4net's so it's packaged in log4net.dll?
I get the following error in the Immediate window when debugging:
log4net:ERROR XmlHierarchyConfigurator: Could not create Appender [HTTPAppender] of type [HTTPAppender.HTTPAppender,HTTPAppender]. Reported error follows. System.IO.FileNotFoundException: Could not load file or assembly 'HTTPAppender' or one of its dependencies. The system cannot find the file specified. File name: 'HTTPAppender' at System.RuntimeTypeHandle._GetTypeByName(String name, Boolean throwOnError, Boolean ignoreCase, Boolean reflectionOnly, StackCrawlMark& stackMark, Boolean loadTypeFromPartialName) at System.RuntimeTypeHandle.GetTypeByName(String name, Boolean throwOnError, Boolean ignoreCase, Boolean reflectionOnly, StackCrawlMark& stackMark) ...etc
Here's the log4net section of the xml file:
<log4net>
<appender name="HTTPAppender" type="HTTPAppender.HTTPAppender,HTTPAppender">
<evaluator type="log4net.Core.LevelEvaluator,log4net">
<threshold value="WARN"/>
</evaluator>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="#%level - %message" />
</layout>
</appender>
<root>
<level value="ALL" />
<appender-ref ref="HTTPAppender" />
</root>
<logger name="log4netErrorLog" >
<level value="DEBUG" />
<appender-ref ref="HTTPAppender" />
</logger>
</log4net>
If you are using any non standard assemblies, put them in the application directory together with your assembly. If that doesn't help, try giving your assembly a strong name and using the full name in the log4net config file. you can also try putting it into GAC.
