Because servlets, like applets, do not take constructors. They
are "constructed" (instantiated) by their respective containers
within their respective contexts (a browser with an applet, a
container with a serlvet). Instead of a constructor, use the
servlet init() method to initialize your counter:
import java.io.*;
import javax.servlet.http.*;
import javax.servlet.*;
public class CounterCons extends HttpServlet {
int count;
public void init( ServletConfig config) throws
ServletException {
super.init( config);
count = 1122;
}
public void doGet(HttpServletRequest req,HttpServletResponse
res) throws IOException {
PrintWriter out = res.getWriter();
count++;
out.println( count);
}
}
Cheers!
Mark
