Out.flush() not working

Question

I can't get the out.flush to work. The page is paused until all values are finished then it is displayed. Here is my example code.
<pre>
import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class MyTest extends HttpServlet {
     public void init(ServletConfig conf) throws ServletException {
super.init(conf);
public void service(HttpServletRequest req, HttpServletResponse res)
throws IOException {
// res.setContentType("text/html"); //this nor the one below works
res.setContentType("multipart/x-mixed-replace;boundary=\"boundary\"");
PrintWriter out = res.getWriter();
for(int x=0;x<3;x++){            
     out.println("<br>x = "+x);
     out.flush();
          try{
                    Thread.sleep(1000); //in milliseconds - 1000 milliseconds = 1 second
               catch(InterruptedException ie){}
</pre>

Answer 1

You were hoping that the output of the servlet would be sent piece by piece to the client browser as you generated it? That is not how it works. Nothing is sent until you return from the service method. It is possible to do what I think you were hoping, but you have to work with the browser and have it refresh periodically. I have seen examples of that but I am not competent to try to explain it.
