Log4j

[Mohit Agarwal]

Hi,

I am trying to use log4j (version log4j-1.2.8.jar ).The server is Tmcat 5.5.9
I made a Initializelog4j Servlet so as to initialize it on server start up.
The code for which is :

 
    import javax.servlet.*;
import javax.servlet.http.HttpServlet;
import org.apache.log4j.*;
import java.io.File;
 
public class InitializeLog4j extends HttpServlet {
 
  public void init(ServletConfig config)throws ServletException {
     super.init(config);
     String filePath = config.getInitParameter("props");   
     System.out.println("The Init Param is :"+filePath);
 if(filePath == null || filePath.equals("")){
   System.err.println("Error: In reaching log4j Config file ");
       throw new ServletException();
 } 
 else{
         
 filePath = getServletContext().getRealPath("/") +filePath;
 System.out.println("FilePath is :"+filePath);
 try {
  File f= new File(filePath);
  if(f.exists()) System.out.println("Props File Exists");
  PropertyConfigurator.configure(filePath);
         }catch(Exception e)
 {
   e.printStackTrace();
 }
 Logger log = Logger.getLogger(InitializeLog4j.class);
 log.info("Congrats you had initialize the logger successfully");
 }
  }
 
}
 

And the web.xml is (Snippet from it):

 
       <!--  Servlet for Initializing the Logger -->
 <servlet>
      <servlet-name>setup</servlet-name>
      <servlet-class>com.overture.campus.displaytag.InitializeLog4j</servlet-class>
      
      <init-param>
      <param-name>props</param-name>
        <param-value>WEB-INF\classes\log4j.properties</param-value>
      </init-param>
 
      <load-on-startup>1</load-on-startup>
</servlet>
 

<servlet>
  <servlet-name>action</servlet-name> 
  <servlet-class>org.apache.struts.action.ActionServlet</servlet-class> 
  <init-param> 
    <param-name>config</param-name> 
    <param-value>/WEB-INF/struts/struts-config.xml</param-value> 
  </init-param>
 
    <load-on-startup>2</load-on-startup>
  </servlet>
 
  <!-- Standard Action Servlet Mapping -->
  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
 

Now when i start Tomcat , i get the
ERROR:Cannot read the configuration file. Please check the path of the config init param in web.xml .


I don't know where i am wrong .

Please provide help regarding this ,

Thanks,
Mohit.
