about sendRedirect

sendredirect : i know taht We cannot call this method if the response is committed�that is,if the response header has already been sent to the browser
but when i write it after commiting response no exception thrown ,why

PrintWriter out = response.getWriter();
try {
out.println("<html>");
out.println("<head>");
out.println("<title>NewServlet</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>NewServlet at "
+ request.getContextPath () + "</h1>");
out.println("</body>");
out.println("</html>");
response.sendRedirect("http://www.cnn.com");

the response buffer is just filled.... it is not committed....

or out.flush() not called yet...

thanks Abinesh for your reply
manuly flush response and still no exception

PrintWriter out = response.getWriter();
try {
out.println("<html>");
out.println("<head>");
out.println("<title>NewServlet</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>NewServlet at "
+ request.getContextPath () + "</h1>");
out.println("</body>");
out.println("</html>");
out.flush(); // flush response
response.sendRedirect("http://www.cnn.com");

i see a try{ in your program... what exception are you handling??

because some programmers handle it this way...
try{
}catch(Exception e){}

This is wrong...
Please post the catch also...

I tried this :

and it throws exception on console.

Thanks,
