Hi Guys:
I have an action class that delegate to the business layer for
processing. Sometimes it takes a long time to do the processing. I would like
to have a timeout of say 2 minutes, I couldnot implement the timeout in
the jsp page, because it is the action class which is doing the
processing logic and until the execute method returns, the jsp is never
executed. So How could i implement the time out in the action class.
I tried to implement a timer using the timer class. but still it
doesnot work, the response is not flushed until the execute method returns,
that means the time it take to finish the processing of the business
logic.
-- code for timer--
new TimerTask(){
run()
{
System.out.println("timer ended");
ActionErrors errors = new ActionErrors();
errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError("error.timeout"));
if (!errors.isEmpty())
request.setAttribute(Globals.ERROR_KEY, errors);
try
{
PrintWriter out = response.getWriter();
out.write("timeout");
out.flush();
// response.sendRedirect(request.getContextPath());
// response.flushBuffer();
System.out.println("send to browser");
}
catch(IOException ex)
{
System.out.println("IO EXCEPTION");
}
}
}
even though i did write something to the response stream, the response
is not send until the execute method returns. any ideas why?
I believe someone might have done this and could help out .
Thank you for your time and effort. a sample code will be greatly
appreciated
cheers
