RE: Cannot create log from vb.net class library .dll

[Dahl, Scott \(CMA Consulting\)]

I was making these changes you suggested and somehow everything started
working.  I don't even know what I did :-(, if I remove your internal
logging config entries, it still works.  I must have had something out
of sync on the box I was deploying changes to.

Weird thing now is that the log entries appear out of order, but at
least I'm getting them all.  

Thanks for your response.

I'd recommend turning on internal log4net logging. It may be because
your FileAppender is attempting to write to
'\windows\system32\GenericInterface.log' instead of where you really
want it to. Adding this code to your App.Config will tell log4net to log
its internal errors to System.Diagnostics.Trace which will be captured
to a file:

    <appSettings> 
        <add key="log4net.Internal.Debug" value="true" />
    </appSettings>
    <system.diagnostics>
        <trace autoflush="true">
            <listeners>
                <add name="textWriterTraceListener" 
                    type="System.Diagnostics.TextWriterTraceListener"
                    initializeData="C:\\log4net.txt" />
            </listeners>
        </trace>
    </system.diagnostics>

Here's a stripped down version of the current class library dll code:

     

   Imports System.IO

     

   ' We want this assembly to have a seperate logging repository to the 

   ' rest of the application. We will configure this repository
seperatly.

   '<Assembly:
log4net.Config.AliasRepository("trafficRouter.trafficRouter")> 

   '<Assembly: log4net.Config.XmlConfigurator(Watch:=True)> 

     

   Public Class trafficRouter

       Private db As New dbConnection

       ' Create a logger for use in this class

       Private Shared ReadOnly l As log4net.ILog =
log4net.LogManager.GetLogger("default")

     

       Public Sub New()

           Try

               log4net.Config.XmlConfigurator.Configure()

               'log4net.Config.XmlConfigurator.ConfigureAndWatch(New
FileInfo("c:\\ xyz.config"))

               l.Info("Creating Traffic Router.")

               dbConnect()

               l.Info("Done creating Traffic Router.")

           Catch ex As Exception

               l.Error(ex)

           End Try

       End Sub

   End Class

     

   This is the web.config file for the web service which is logging
correctly:

   <?xml version="1.0"?>

   <configuration
xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0";;>

       <configSections>

           <section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler" />

       </configSections>

       <appSettings/>

       <!-- This section contains the log4net configuration settings -->

       <log4net>

         <!-- Define some output appenders -->

         <appender name="LogFileAppender"
type="log4net.Appender.FileAppender">

           <file value=".\\GenericInterface.log" />

           <appendToFile value="true" />

           <layout type="log4net.Layout.PatternLayout">

             <conversionPattern value="%date [%thread] %-5level %logger
- %message%newline" />

           </layout>

         </appender>

     

         <logger name="default">

           <level value="ALL" />

           <appender-ref ref="LogFileAppender" />

         </logger>

       </log4net>  

       <connectionStrings/>

       <system.web>

           <compilation debug="false" />

           <authentication mode="Windows" />

       </system.web>

   </configuration>

     

   Here is the "custom config" I tried using for the class library log:

   <?xml version="1.0" encoding="utf-8" ?>

   <configuration>

       <system.diagnostics>

           <sources>

               <!-- This section defines the logging configuration for
My.Application.Log -->

               <source name="DefaultSource" switchName="DefaultSwitch">

               </source>

           </sources>

           <switches>

               <add name="DefaultSwitch" value="Information" />

           </switches>

       </system.diagnostics>

     

     <!-- Register a section handler for the log4net section -->

     <configSections>

         <section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

     </configSections>

     <!-- This section contains the log4net configuration settings -->

       <log4net>

         <!-- Define some output appenders -->

         <appender name="LogFileAppender"
type="log4net.Appender.FileAppender">

           <file value=".\\trafficRouter.log" />

           <appendToFile value="true" />

           <layout type="log4net.Layout.PatternLayout">

             <conversionPattern value="%date [%thread] %-5level %logger
- %message%newline" />

           </layout>

         </appender>

     

         <logger name="default">

           <level value="ALL" />

           <appender-ref ref="LogFileAppender" />

         </logger>

       </log4net>

   </configuration>

     

   I've come across a few suggestions but none of those have helped at
all.  This is what I've tried different from the current code:

   1)       Explicitly call the
log4net.Config.XmlConfigurator.ConfigureAndWatch function, passing my
custom configuration above, in the constructor.

   2)       Setting an alias repository using: Assembly:
log4net.Config.AliasRepository("trafficRouter.trafficRouter")> and
Assembly: log4net.Config.AliasRepository("trafficRouter")>

   3)       Uncommenting the other assembly line from the class.

     

   I'm pretty new to .net and log4net so please excuse me if I've
stumbled with some terminology or overlooked the obvious.   

     

   Thanks,

   Scott
