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
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>CMIS_NEW</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>/WEB-INF/log4j.properties</param-value> </context-param> <servlet> <servlet-name>TestLog4j</servlet-name> <servlet-class>com.cims.TestLog4jServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>TestLog4j</servlet-name> <url-pattern>/test</url-pattern> </servlet-mapping> </web-app>
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"); } }
