The concept of buffering in servlets

[nebula kodatham]

hi,

The response.reset() of HttpServletResponse should throw IllegalStateException if it is called after the response has been commited. In my code i have used isCommited()to find out if the response is commited and it gives true. After the response is commited i call the reset()which sholud give an exception as expected.But i am not getting any exception......i get the response without any exceptions which should not be the case.Why am i not getting any exception. Can anyone give a small sample code illustrating the usage of reset().


here's my code

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class KeepAlive extends HttpServlet
{
public void service(HttpServletRequest request,HttpServletResponse  response)throws IOException,ServletException
{
response.setContentType("text/html");
PrintWriter out=response.getWriter();


response.setBufferSize(3 * 1024);

out.println("kodatham");
 
for(int i=0;i<9000;i++)
{
out.println("deepthi");
}
 
out.println("kodatham");

if( response.isCommitted() )
{
      out.println( "<br>damned, something has been sent" );
    }

//response.flushBuffer();
response.reset();


}

}

I'm sorry but why on earth do you care? It is bad enough overriding the service() method - that is not considered good practice - but why do you need the reset() to throw an exception? Perhaps it is a bug - you don't tell us what container you're using. But I can't figure out why you want the exception. Is there a good reason or is this a fishing expedition?

Well right now your flushBuffer() call is remarked off.

I am going to move this to the Servlets forum.
