out.flush() not working

[tommycat2]

I have a piece of code which I am using for testing apache. Essentially i need it to print out partial results to the web page before the complete jsp page has finished executing. I used to use apache 1.3x and oracle-jsp engine and with this configuration it seemed to work as expected when using the out.flush() command.
Now that I have upgraded to tomcat 5.0.28 and apache 2.0 when I use out.flush() it has no effect and waits until all of the content for the page has been prepared before commiting it to the web browser.

Here is my test program:

<%@ page language="java" import="java.util.*, java.rmi.*" %>

<%
for (int i=0; i <20; i ++) {

out.println("i="+i+"\n<br>");
out.flush();

try {
Thread.sleep(500);
} catch (Exception ex) {

}
}
%>

thanks for any help

Try this before your loop:

for(int k=0; k<10; k++){
out.print("<!--1234567890-->");
}

I don't know why, but it runs. Perhaps it fills the browser buffer.
