Hi all,
I am new to servlets and am trying to execute a simple counter which has an initial value.
I have the following web.xml file
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
<servlet>
<servlet-name>
counter
</servlet-name>
<servlet-class>
InitCounter
</servlet-class>
<init-param>
<param-name>
initial
</param-name>
<param-value>
&n
bsp; 1000
</param-value>
<description>
The initial value for the counter <!-- optional -->
</description>
</init-param>
</servlet>
</web-app>
and my java program is
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class InitCounter extends HttpServlet {
int count;
public void init() throws ServletException {
String initial = getInitParameter("initial");
try {
count = Integer.parseInt(initial);
}
catch (NumberFormatException e) {
count = 0;
}
}
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/plain");
PrintWriter out = res.getWriter();
count++;
out.println("Since loading (and with a possible initialization");
out.println("parameter figured in), this servlet has been accessed");
out.println(count + " times.");
}
}
I was expecting the counter to start printing from 1001 and so on.....but there seems to be a NumberFormat Exception and hence it is taking counter's intial value as zero.
How to get the counter value to start from 1000 instead of 0 ?
Thanks in advance
