approach was:<br>
* Include slf4j-api in WEB-INF\lib of the war files of the applications<br>
* Include the binding ja slf4j-log4j in WebSphere lib<br>
* Include log4j.xml in JVM classpath external to the war file.<br>
<br>
Only problem is that it doesn't work. It fails with an error on<br>
initializing. Guess my approach is wrong?<br>
<br>
Thanks for any assistance!<br>

Here's the stack trace. Note that slfj-api is found in WEB-INF\lib of the<br>
WAR file:<br>
