Hi,

my first page in my project is a jsp page which selects a network and clicking start button,a dialing process will happen through a servlet which forwards to a jsp page in one frame which selects a network and a stop button and another frame displays which network is selected.if i stop the button in the first frame,the selected network should be stopped and the two frames should be closed and open the jsp page which is used to start the network.
The following code stops the network selected and closes the two frames.But it oens the jsp page which stops the network.

It looks to me that StopServlet is doing the required functionality, so from this servlet forward the request to the page where ever you want.

What exactly do you want? Only a window will appear without any frames?

what i exactly need is on clicking the stop button,the selected network should be stopped and the two frames should be closed and the main page should be displayed again.

Thanks

From StopServlet instead of using forward action, use sendRedirect to the main page that might solve the problem, provided you dont have any scoped attribute values set.

Should work now, in java script instead of location.href use parent.location.href

i.e.

your present code is

location.href=locationRequest;

try with

parent.location.href=locationRequest;

You mean after execution of the servlet, in mozilla its behaving differently with the same redirect url from servlet?

Apart from that I dont find any use of history.forward and document.write in your code.

Thanks a lot .Now its working fine in mozilla too.
instead of using stop as ahref ,I changed stop as button.Now it is working fine.

Thanks again

This is awkward. I've grown a second evil head. I'm going to need a machete and a tiny ad ...
