title: how to set log4j.configuration system variable in WebSphere 7?
body: <p>I have a Java EE 5 web app I'm deploying to WebSphere 7 as an EAR file.</p>
  
  <p>I want my log4j configuration to be external to the EAR file so I can tweak log content when needed without needing to rebuild and redeploy the EAR file.</p>
  
  <p>My understanding is I can specify the location of my log4j.properties file by setting a 
  "system variable" called log4j.configuration. (ex. log4j.configuration=c:/log4j.properties)</p>
  
  <p>My question is, how do I set this system variable in the WebSphere 7 admin console?</p>
  
  <p>Browsing around I see there is <code>Environment &gt; WebSphere Variables</code>, but that doesn't look right because that would be setting a variable for the entire server.  I'm guessing I want to set a system variable just for my application EAR file.</p>
  
  <p>Any help or suggestions is greatly appreciated!</p>
