Craig,
Thanks. But when i try to call the flush() method incrementally during the
execution of the doGet(), the client does not display anything. The browser
keeps loading and displayed everything at the end. I am using Tomcat 4.1.10
for this example.
Thanks for your help.
Sam
public void doGet() {
int count = 0;
response.setBufferSize(1);
PrintWriter out = response.getWriter();
for (int i= 0; i < 10; i++) {
out.println("<h1> Count: ");
out.println(count++);
out.println("</h1>");
System.out.println ("print log count:" + count);
out.flush();
response.flushBuffer();
Thread.sleep(5000);
}

Yes, you can call writer.flush() or response.flushBuffer().
See the servlet spec for all the details:
