Quartz.Net - Common Logging with log4net

Question

I'm trying to implement Quartz.Net. As long as there is no logging configured everything works (the debug output shows "no configuration section found - suppressing logging output").

When logging is enabled I'll get the following error: Failed obtaining configuration for Common.Logging from configuration section 'common/logging'.

Inner exeption: An error occurred creating the configuration section handler for common/logging: Unable to create type 'Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4net'

I used several resources as this one to varify my configuration, but as far as I see it should be correct.

My app.config:

  <configSections>
    <section name="quartz" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    <sectionGroup name="common">
      <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
    </sectionGroup>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>
  <common>
    <logging>
      <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4net">
        <arg key="configType" value="INLINE" />
      </factoryAdapter>
    </logging>
  </common>  
  <log4net>
    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
      <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%-6p%d{yyyy-MM-dd hh:mm:ss} – %m%n" />
      </layout>
    </appender>
    <root>
      <level value="DEBUG" />
      <appender-ref ref="ConsoleAppender" />
    </root>
  </log4net>
  <quartz>
    <add key="quartz.scheduler.instanceName" value="Driver.Service.Scheduler" />
    <add key="quartz.threadPool.type" value="Quartz.Simpl.SimpleThreadPool, Quartz" />
    <add key="quartz.threadPool.threadCount" value="10" />
    <add key="quartz.threadPool.threadPriority" value="2" />
    <add key="quartz.jobStore.misfireThreshold" value="60000" />
    <add key="quartz.jobStore.type" value="Quartz.Simpl.RAMJobStore, Quartz" />
  </quartz>

I referenced the following assemblies:
quartz.dll, version 2.01.100
common.logging.dll, version 2.0.0.0
common.logging.log4net.dll, version 2.0.0.0
log4net.dll, version 1.2.10.0

I cannot find a reason for the error given. All help is welcome, apparently I forget something...

Answer 1

Can you check that Common.Logging.Log4net.dll is being copied to your bin output folder.

Also are you sure you don't have a inner exception on your inner exception (or maybe several levels of inner exceptions) ?

Answer 2

We had similar situation when we upgraded to the new version of Common.Logging.Log4Net where the DLL name to changed to Common.Logging.Log4Net1211 from Common.Logging.Log4Net.

So, we modified the configuration file to change DLL name:

<factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net1211">

Anyway, the error definitely indicates missing DLL.

Answer 3

Im not sure, but in your common/logging config section, one time its written log4net and one time its log4Net (capital letter):

  <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4net">
