Hello, I will try to be clear with my english...

I want the user on the client side to be able to save the results shown in the JSP page to a new XLS file.

When he clicks on a button, a popup appears (like "file-save as" standard in web pages), User choose his folder and gives the name of the file to be created.
My servlet will generate the result file with the name input by the user into his folder using outputStream class.

What is the way to able the user to choose his folder ? I can't use "input type file" because the file must exist with this input type.

I hope my request to be clear...

Thank you for your help.

When the button is clicked, submit to a servlet that streams the file to the browser with the appropriate content-type and content-disposition headers. The browser will take care of everything else.

Search this and the Servlets forum for terms like "content-disposition" for concrete examples.

Thank you for your quick answer, but, what I really need is

what kind of "button" or "input type" can I use to make the same think that "File -save as" : Go to client directories, choose the good one etc...

It is not "input type="file" , because file must already exist.

Do you know the html method to do this ?

Regards,

Mariane

It's not something that's done on the HTML side.

As bear mentioned, the "Content-Disposition" header coming from the server is what triggers that.

OK, thank you very much, I didn't understand the first time, but know, I just tryed to use "content-disposition" and it works fine.
