I currently do the following.
See the 3 or 4 sections of code below.
I have a servlet that is loaded at the time tomcat starts.
Pay no attention to the crap coding in this file, but you get the idea
BEGIN EimplementLogger.java ///
package whateverpackage.log;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import org.apache.log4j.xml.*;
import javax.naming.NamingException;
import javax.naming.Context;
import javax.naming.InitialContext;
public class EimplementLogger extends HttpServlet {
DOMConfigurator domConfig;
public void init() throws ServletException {
// init code here
domConfig = new DOMConfigurator();
// point to log4j configuration file
Context ctx = null;
String log4jxmlfilepath = null;
try {
ctx = new InitialContext();
} catch (NamingException e) {
// System.out.println(Couldn't build an initial context : + e);
return;
}
try {
log4jxmlfilepath = (String)(ctx.lookup(java:/comp/env/log4jxmlfilepath));
} catch (NamingException e) {
System.out.println(JNDI lookup failed : + e);
}
domConfig.configure(log4jxmlfilepath + log4j.xml);
}
}
/ END EimplementLogger.java
In my web.xml i have the following to start this servlet up.
servlet
servlet-name
EimplementLogger
/servlet-name
servlet-class
whateverpackage.log.EimplementLogger
/servlet-class
load-on-startup5/load-on-startup
/servlet
then in the class (bean) that has no idea about the context i have the
following:
protected org.apache.log4j.Logger logWriter =
org.apache.log4j.Logger.getLogger(nameoffiletoappearinlog);
and i use it like so
logWriter.debug(here is a debug statement);
hope that helps

AB G'day,
AB Can anyone expand on this further and explain how to use a Log4j logger
AB reference in beans that do not have a notion of what the underlying servlet
AB context is? The only way I can see how to get this to work is to pass the
AB logger reference as an argument in the bean's constructor.
AB My query does seem to be out of context for this list so my apologies in
AB advance.

How are you logging in your servlets? Are you using
System.out/System.err? If so, don't use them, and instead use the
ServletContext#log(..) methods.
Actually, they are mostly beans with no ServletContext :(
