Websphere 3.5, Log4j 1.2.7

[Sean Sullivan]

Is anybody using Log4j 1.2.7 in Websphere 3.5?
I installed the log4j JAR file and a copy of
log4j.xml
The problem is that Log4j is having trouble loading log4j.dtd
This is surprising because log4j.dtd is contained inside the log4j JAR file. I have not modified the DTD or the JAR.
Any advice?

I've been trying to utilize Log4j 1.2.7 in Websphere 3.5
Log4j attempts to load a file called log4j.dtd using the getResource() method in java.lang.Class
The getResource() method is always returning null.
I searched IBM's online support and there appears to be a bug related to getResource()

I'm using log4j1.2.1 with WAS 4.0.
I just put it in the WEB-INF lib of the application's war file
