Step 1: create your web application in eclipse
Step 2: Create web.xml as fallows
Step 3: Create servlet which initialized your log4j configuration
Step 4: Create log4j.properties and place into the classpath
Step 5: Create your tester servlet as fallows
Step 2: Create web.xml as fallows

Step 3: Create servlet which initialized your log4j configuration
package com.cims;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import org.apache.log4j.PropertyConfigurator;
public class Log4JServlet extends HttpServlet {
public void init() throws ServletException{
String log4jfile = getInitParameter("log4j-init-file");
if(log4jfile != null){
String propfile = getServletContext().getRealPath(log4jfile);
PropertyConfigurator.configure(propfile);
}
}
}
Step 4: Create log4j.properties and place into the classpath
log4j.rootLogger=INFO, CMISAppender log4j.appender.CMISAppender=org.apache.log4j.ConsoleAppender log4j.appender.CMISAppender.layout=org.apache.log4j.PatternLayout log4j.appender.CMISAppender.layout.ConversionPattern=%-4r [%t] %-5p %d %c %x - %m%n
Step 5: Create your tester servlet as fallows
package com.cims;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.log4j.Logger;
public class TestLog4jServlet extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 1L;
static Logger logger = Logger.getLogger(TestLog4jServlet.class);
public void doGet(HttpServletRequest req,HttpServletResponse res)
throws ServletException,IOException{
logger.info("Starting the "+this.getClass().getName()+" doGet() Method");
res.setContentType("text/html");
PrintWriter out = res.getWriter();
out.println("Log4j Debugger Example");
logger.info("Exiting the "+this.getClass().getName()+" doGet() Method");
}
}
