If del out.flush(),browser can redirect to www.yahoo.com.But don't show "hello".
who can tell me, why?

Hi,
replace your code with this one
public void doGet(HttpServletRequest request,HttpServletResponse response)throws ServletException, IOException { PrintWriter out = response.getWriter(); out.println("<html><body>Hello!</body><script>window.location.href='http://www.yahoo.com'</script></html>");
Please let me know, if still have problems
Thanks
Suresh

you can't call "flush" before calling sendRedirect.
as a general rule, flush means your response is over, nothing more. no more changes in status code, headers, or response-body. Otherwise, IllegalStateException. Tomcat doesn't give your that exception, because it is lenient. It just ignores the output after flush.

Thanks!

This line of code
response.sendRedirect("http://www.yahoo.com");
after out.flush() does produce the IllegalStateException in Tomcat also. Check your log file (C:\jakarta-tomcat-4.0.3\logs\localhost_log_date.log) The exception is logged in there.
Since the response is already commited , there is no way to send this exception to browser again. This is the reason you do not see any exception displayed in browser.
If you try to make a try ... catch block then you can realize that the IllegalStateException is reaised indeed.
