Title: Message

I'm stuck.  I can't figure out what would cause the "No appenders could be found for logger" error.  Is it possible that log4net isn't reading the config file corrently?

 

Thanks,

 

Jason

All,

 

      Per Erik's suggestion I turned on debugging and downloaded sysinternal's DebugView and found the following 2 entries:

 

[2136] log4net: DefaultRepositorySelector: defaultRepositoryType [log4net.Repository.Hierarchy.Hierarchy]

[2136] log4net: DefaultRepositorySelector: creating repository for assembly [EmailService, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]

[2136] log4net: DefaultRepositorySelector: assembly [EmailService, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null] using domain [log4net-default-domain] and repository type [log4net.Repository.Hierarchy.Hierarchy]

[2136] log4net: DefaultRepositorySelector: creating repository for domain [log4net-default-domain] using type [log4net.Repository.Hierarchy.Hierarchy]

[2136] log4net:ERROR Logger: No appenders could be found for logger [Company.Project.EmailService.EmailServiceStarter]

[2136] log4net:ERROR Logger: Please initialize the log4net system properly.

 

 

      Below is my EmailService.exe.config.  What am I missing?

 

Thanks,

 

Jason

Try debugging to see if you are getting configured right. Make sure the config file is getting read properly.

 

If the event log AND the file logging both fail, that points to something higher in the tree.

 

and enable debugging on log4net.

Brette,

            What about Windows Service using the rolling file appender?  If the exe I registered as a Windows Service is stored in C:\MyService, technically, the log file should be created in there as well right?  What stumps me is that Filemon from Sysinternals did not detect any permission denied tries that may indicate some sorts of a user/file permission cause.

Thanks,

Jason

I have run into this problem when trying to log to event log. It ended up being that the user that was running log4net did not have access to log to the event log. Have you tried taking out the event log appender and seeing if the file appender is working?

I'm having trouble getting log4net working in my Windows Service application.  Root is setup to use both event log appender and rolling log file appender but nothing is logged  (No exception thrown either).  What is the best way to troubleshoot?

 

Thanks,

 

Jason
