[jira] Commented: (LOG4NET-277) Registering a custom Object
Renderer in configuration file
[ https://issues.apache.org/jira/browse/LOG4NET-277?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12931094#action_12931094 ]
Daniel Shoubridge commented on LOG4NET-277:
-------------------------------------------
I found a work around:
include ", RootNameSpace":
<renderer renderingClass="RootNameSpace.Namespace.RendererClass, RootNameSpace" renderedClass="RootNameSpace.NameSpace.ClassToRender, RootNameSpace" />
I can't say why this works, but looks like it helps log4net find the assembly.

> Key: LOG4NET-277
> URL: https://issues.apache.org/jira/browse/LOG4NET-277
> Project: Log4net
> Issue Type: Bug
> Components: Other
> Affects Versions: 1.2.10
> Environment: Windows .Net WebService
> Reporter: Daniel Shoubridge
>
> When you include the line:
> <renderer renderingClass="RootNameSpace.Namespace.RendererClass" renderedClass="RootNameSpace.NameSpace.ClassToRender" />
> in the configuration file and call:
> log4net.Config.XmlConfigurator.ConfigureAndWatch(New IO.FileInfo(logfile))
> in global.asax, you get a TypeLoadException. Log4Net internal debugging outputs the following:
> log4net:ERROR OptionConverter: Could not instantiate class [LogLibrary.Log4NetObjRenderers.PdaLogObjRenderer].
> System.TypeLoadException: Could not load type [LogLibrary.Log4NetObjRenderers.PdaLogObjRenderer]. Tried assembly [log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821] and all loaded assemblies

> Work Around:
> 1, If you then stop the web server
> 2, and comment out the <renderer line in the configuration file,
> 3, start the web service again,
> 4, then after it has started (global.asax has been processed)
> 5, uncomment the <renderer line
> 6, the renderer will now work
