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.

Jake,
Putting the properties file under /web-inf/config is what I really wanted to achieve, but I am not be able to make it work. I uses the following to initialised the log4j package.
package com.log;
import org.apache.log4j.*; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;
public class Log4jInit extends HttpServlet {
public void init() {
String servletContainer = getServletContext().getRealPath("/");
// The exact path to the config file is in servlet mapping String file = getInitParameter("log4j"); Logger logger = Logger.getLogger(getClass());
// if the log4j-init is not set, then no point in trying if (file != null) {
BasicConfigurator.configure(); BasicConfigurator.resetConfiguration(); PropertyConfigurator.configure(servletContainer+file);
// Sent into to system.log logger.info("Logging system initialised successfully");
}
}
public void doGet(HttpServletRequest req, HttpServletResponse res) { }
}
I uses the following for my database properties which I have no luck in getting it to read /web-inf/config too:
Properties Prop = new Properties(); try {
InputStream configStream = getClass().getResourceAsStream("/config/database.properties"); Prop.load(configStream); configStream.close();
} catch(IOException e) {
System.out.println("Error: Cannot laod configuration file "); }
Do you have a sample code that works? Thank you.

If you are going to create a "config" dir, why not do it directly under
WEB-INF rather than where classes are put? You can load up an input stream using context.getResourceAsStream("WEB-INF/config/log4j.properties") and feed that info a Properties object, then send that into PropertyConfigurator.configure(Properties) or load up a URL using context.getResource("WEB-INF/config/log4j.properties") and send that info PropertyConfigurator.configure(URL).
Of course you can still do this even if you leave the "config" directory under "WEB-INF/classes" and use the same technique above. Whatever you
feel comfortable with. I just like not cluttering my classpath with non-classes.
