It would help if you actually obtained your servlet context. Right now, it is null.
ServletContext context = this.getServletContext()

Jake,
Thank you for your time. I have made the changes to the code as you have suggested. It compiled without problem. However, it does not seems to initiate the Log4j Tag Library. Have I missed out anything?

You need to look at my code closer. "context" is a ServletContext. You can use it to access stuff anywhere in the webapp.
URL url = context.getResource("/WEB-INF/config/log4j.properties"); PropertyConfigurator.configure(url);
And, of course, you can also use the InputStream way if you want, but the URL way is a bit simpler.
One thing to note. In my original code, I had forgotten to prefix WEB-INF with a "/". That is fixed in the code above.
