Problem with running multiple servlet in same webapplication with tomcat 3

Question

Hi all,
I am using Tomcat 3.0 as webserver with jdk1.3, Servlet 2.0,
Templates for html file and oracle 8i on UNIX platform.
I have problem with multiple servlet running same webapplication.
There are two servlet used in my application. 1) GenServlet.class
               and 2) ServletForPrinting.class
All of my pages go through GenServlet.class which reads some property files
and add header and footer in all pages.
I want reports without header & footer that is not possible through GenServlet in my application.
So I have used another servlet called ServletForPrinting --- just for reading html file.
It is as follow:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ServletForPrinting extends HttpServlet {
public void service (HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException
// set content-type header before accessing the Writer
response.setContentType("text/html");
PrintWriter out = response.getWriter();
File f1 = null;
String report = null;
String path = request.getPathInfo();
try{
String p = "/var/home/latif/proj/webapps/WEB-INF/classes" + path;
System.out.println(p);
f1 = new File(p);
p = null;
if (f1.exists()) {
FileReader fr = new FileReader(f1);
BufferedReader br = new BufferedReader(fr);
report = new String();
while ((report = br.readLine()) != null) {
out.println(report);
}catch(Exception e) {
out.close();
report = null;
path = null;
f1 = null;
} // end class
It works fine and display report properly.
But now Problem is that if report is refreshed many times subsequently,
WebServer will not take any new change in any of java file used in web-application.
It works with the previous class only and not with updated one.
Then I need to touch it. As soon as I touch it, webserver will take updated class file.
Anybody has any idea regarding these situation?
Is there any bug in my ServletForPrinting.java ?
Any solution ????? Please suggest me.
Suggestion from all are invited. That will help me a lot.
Thanks in advance

I solved the problem, I just had to wire the blocks in a sequential way (I still don't know why, but it works).
Feel free to delete this topic.
I would strongly suggest at least reading this tutorial to give you an idea of why your fix worked (or maybe only appeared to work).  Myself, I never just throw up my hands and say, "Whatever," and wash my hands of the situation without trying my best to understand just what fixed it.  Guranteed you'll run into the same/similar problem and this time your fix won't work.
Please do yourself a favor and try to understand why it is working now, and save yourself (or more likely, the next poor dev to work on this project) some heartache.
