java.IO.EOFException when deploying war file

[James Dekker]

Hello there, I am having a problem when deploying my application (via a war file) in Tomcat 5.5.9.

The exception I am getting is this:

log4j:WARN No appenders could be found for logger (org.apache.catalina.session.ManagerBase).

My Servlet Code:

package org.acme.logging;
 
import org.apache.log4j.PropertyConfigurator;
 
import java.io.File;
 
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
 
public class Log4jInitServlet extends HttpServlet {
    public void init() throws ServletException {
        String prefix = getServletContext().getRealPath("/");
        String file = getInitParameter("log4j-init-file");
        File propFile = new File(prefix+file);
        if(!propFile.exists()){
            System.out.println("log4j.properties not found, " + propFile.getAbsolutePath());
        }
        PropertyConfigurator.configureAndWatch(propFile.getAbsolutePath(),10000);
    }     
}

This is my deployment descriptor (web.xml) file:

<!DOCTYPE web-app 
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
    "http://java.sun.com/dtd/web-app_2_3.dtd">
 
<web-app>
 
    <display-name>Acme</display-name>
    <description>
        Acme Application
    </description>
 
    <servlet>
      <servlet-name>AcmeServlet</servlet-name>
      <servlet-class>org.acme.AcmeServlet</servlet-class>
    </servlet>
 
    <servlet-mapping>
      <servlet-name>AcmeServlet</servlet-name>
      <url-pattern>/app</url-pattern>
    </servlet-mapping>
    
    <servlet>
       <servlet-name>log4j-init</servlet-name>
       <servlet-class>org.acme.logging.Log4jInitServlet</servlet-class>
       <init-param>
           <param-name>log4j-init-file</param-name>
           <param-value>WEB-INF/log4j.properties</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
   </servlet>
    
</web-app>

Its saying that it can't find the class but under my TOMCAT_HOME/WEB-INF/classes directly, I can see the Log4jInitServlet.class file under org/acme/logging...

What is it that I am doing wrong?

Thank you,

JD
