OS : Windows 2000
WAS : Tomcat 4.1.30
파일경로 : WebApp = C:\Apache_Group\Tomcat4130\webapps\ROOT
1. Log4j 초기화에 필요한 서블릿 생성
파일경로 : %WebApp%/WEB-INF/classes/Log4jInit.class
------------------------------------------------------------------------------------
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import org.apache.Log4j.PropertyConfigurator;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.PrintWriter;
import java.io.IOException;
public class Log4jInit extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=EUC-KR";
//Initialize global variables
public void init() throws ServletException {
String prefix = getServletContext().getRealPath("/");
String file = getInitParameter("Log4j-init-file");
// if the Log4j-init-file is not set, then no point in trying
if(file != null) {
PropertyConfigurator.configure(prefix+file);
}//end if
}//end init
//Process the HTTP Get request
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
//Process the HTTP Post request
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
//Clean up resources
public void destroy() {
}
}

2. 톰켓 서버 작동시 초기화 서블릿 호출 web.xml 에 추가할 내용
파일 경로 : %WebApp%/WEB-INF/web.xml
------------------------------------------------------------------------------
<servlet>
<servlet-name>Log4jinit</servlet-name>
<servlet-class>Log4jInit</servlet-class>
<init-param>
<param-name>Log4j-init-file</param-name>
<param-value>WEB-INF/classes/Log4j.properties</param-value>
<description>Log4j.properties</description>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Log4jinit</servlet-name>
<url-pattern>/Log4jinit</url-pattern>
</servlet-mapping>
-------------------------------------------------------------------------
3. Log4j.properties 파일 ( 콘솔에서 로그보이기 셋팅 )
파일 경로 : %WebApp%/WEB-INF/classes/Log4j.properties
-----------------------------------------------------------------------------
# For the general syntax of property based configuration files see the
# documenation of org.apache.Log4j.PropertyConfigurator.
# The root category uses the appender called A1. Since no priority is
# specified, the root category assumes the default priority for root
# which is DEBUG in Log4j. The root category is the only category that
# has a default priority. All other categories need not be assigned a
# priority in which case they inherit their priority from the
# hierarchy.
# Set root logger level to DEBUG and its only appender to A1.
Log4j.rootLogger=DEBUG, A1
# A1 is set to be a ConsoleAppender.
Log4j.appender.A1=org.apache.Log4j.ConsoleAppender
# A1 uses PatternLayout.
Log4j.appender.A1.layout=org.apache.Log4j.PatternLayout
Log4j.appender.A1.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
