Subject Re: lo4j2.xml in EAR
Date Mon, 03 Nov 2014 19:51:15 GMT
The first smart thing to do in Wildfly 8.1 is install a common instance of
log4j2. You do this by creating a module. Here are my steps:

1. Go to <WildFlyHome>/modules
2. Create folders org/apache/log4j2/main
3. Drop in the api jar.
4. Create a module.xml with this content:

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="org.apache.log4j2">
        <resource-root path="log4j-api-2.1.jar"/>

PS: I could have also dropped in the "core" jar but I am being
conservative. Since I can't get anything to work, this is the minimal.

Then inside my ejb-jar project, I create myself a
META-INF/jboss-deployment-descriptor.xml file like this:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">
      <module name="org.apache.log4j2" />

That should automatically map the jar into my module's classpath. I've done
this before but I am obviously missing something because it's not working.
If anyone can help by following these steps and figuring this out, I'd be
happy to hear someone's success story.
