What do you mean by this? Should I do something special in your solution ContextClassLoaderSelector that you put in the sandbox?
There is both a ContextClassLoaderSelector and a ContextJNDISelector. Which one do you use? Actually, from what you had written, it seemed to me that you wrote your own based on what I wrote and didn't use exactly what I wrote, so I was wondering what you did.
Oh, you know what, I bet you are using a very old version of all this stuff. I recommend an upgrade. Check out the latest log4j-sandbox stuff. You can control which selector you use by doing this....
<context-param>
<!-- preferred repository selector. "preferred" because if one
is already installed, this choice is ignored. -->
<param-name>log4j-selector</param-name>
<param-value>org.apache.log4j.selector.ContextJNDISelector</param-value>
</context-param>
<context-param>
<!-- relative path to config file within current webapp -->
<param-name>log4j-config</param-name>
<param-value>WEB-INF/log4j.xml</param-value>
</context-param>
<context-param>
<param-name>log4j-cron</param-name>
<param-value>0</param-value>
</context-param> <listener>
<listener-class>
org.apache.log4j.servlet.InitContextListener
</listener-class>
</listener>

<env-entry>
<description>JNDI logging context for this webapp</description>
<env-entry-name>log4j/logging-context</env-entry-name>
<env-entry-value>SomeStringUniqueForThisContext</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>Using the JNDI selector might make things less susceptible to hard-to-debug classloader issues.

Done.

That is exactly what I do.

Based on below, I would move your log4j.xml into WEB-INF, and move it out of WEB-INF/classes. That will get rid of any confusion with automatic configuration.
Beyond what I've told you, I'm really not sure why your server config stops being output. It makes me think that, somehow, the separate repository isn't being used when the webapps configure themselves. You'll have to test some things out. Not sure I can help much more here.

I'm using your servlet context listener with this in my web.xml:
--------------------------------------------------- !--========================================================== - Log4j config parameters ==========================================================--> <context-param> <param-name>log4j-selector</param-name>
<param-value>org.apache.log4j.selector.ContextClassLoaderSelector</param-val ue> </context-param> <context-param> <param-name>log4j-config</param-name> <param-value>WEB-INF/classes/log4j.xml</param-value> </context-param> <context-param> <param-name>log4j-cron</param-name> <param-value>0</param-value> </context-param>
<listener>
<listener-class>org.apache.log4j.servlet.InitContextListener</listener-class > </listener> ---------------------------------------------------
>Otherwise, you can set something up in the container to set the >repository selector before any webapps get deployed.
For this solution, I have to investigate more on how to achieve this with Resin.
