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?

package com.log;
import org.apache.log4j.*;
import java.net.*;
import javax.servlet.*;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class Log4jInit extends HttpServlet {
public void init() {
try {
ServletContext context = null;
URL url =
context.getResource("/WEB-INF/config/log4j.properties");
BasicConfigurator.configure();
BasicConfigurator.resetConfiguration();
PropertyConfigurator.configure(url);
} catch (MalformedURLException e) { e.printStackTrace();}
Logger logger = Logger.getLogger(getClass());
logger.info("Logging system initialised successfully");
}
public void doGet(HttpServletRequest req, HttpServletResponse res) { }
}

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.
