The servlet below works under Linux with Sun JDK 1.2.2, tomcat 3.3 dev to
Netscape 4.7 on NT.
Different browsers handle push differently, you'll need to experiment.

public class TestPushServlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse resp) {
try {
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
out.println("<html><body>");
for (int i = 0; i < 10; i++) {
Thread.sleep(2000);
out.println(i + "<br>");
out.flush();
}
out.println("</body></html>");
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
