Servlets

[frankee]

Hi!
My problem is as follows: there shall be sent a form via POST request from
a html or a swf file to a servlet which is located on a server. This servlet
only processes the data of the form in some without sending back anything.
On the client side instead there is always a return page appearing which
says that the requested page contained no data. (????) All I want is no return
at all: the sending source (swf or html) shall only send the data and continue
as if nothing happened. Who could give me soem hint ? I would be grateful
for anything !
Thanks in advance !

You must return something from a servlet. Once the browser sends a request,
it will wait until it receives a response to this request. In your case,
perhaps you should send the same form that is already visible in the
browser. (Aren't you going to confirm to the user that the data was
received successfully?)

HTTP protocol has specific hearders for sending the response. If you send
204 which is no data browser doesn't do anything. In your servlet after
processing your data send 204 response. In HttpServletResponse you have
method named setStatus which takes int as pararmeter. You can write like
this

public void doPost(HttpServletRequest request, HttpServletResponse resp)
throws ServletException, IOException
{
resp.setStatus(HttpServletResponse.SC_NO_CONTENT);
return;
}
