Hello,

I would like to allow my user to download a file thanks to a windows
download box. I succeed while using a simple page with a rialto pop-up
and a button "download" but now that I've integrated it in my
application, it doesn't work anymore.

-----------------------------------------------------------------
My servlet :
response.reset();
response.setHeader("Expires", "0");
response.setHeader("Cache-Control","must-revalidate, post-check=0,
pre-check=0");
response.setHeader("Pragma", "public");
response.setContentType("application/x-download");
response.setHeader("Content-Disposition", "attachment; filename=\"" +
chemin + "\"");
               
OutputStream os = response.getOutputStream();
InputStream is = url.openStream();
int count;
byte buf[] = new byte[4096];
while ((count = is.read(buf)) > -1) {
    os.write(buf, 0, count)
}
is.close();
os.flush();
               
-------------------------------------------------------------------

The result is that a rialto pop-up is opened. Its title is "response"
(like when I've a servlet error) and its content corresponds to the
content of the xml file download by the user.

Thanks by advance

Hello,

With some other tests, I've found that if the form isn't in
Asynchronous mode, it works, but not if it is in Asynchronous mode.

--------------------------------------------------------------------

this is my form :
<% String url = response.encodeURL("saving.do"); %>
                                <rialto:form name="SavingForm"
                                        url="<%= url %>" boolAsynch="false"
                                        boolWithFenWait="false" method="post">
                                       
                                        <rialto:button name="SAVE" title="Save"
                                                top="180" left="360" alt="Save"/>
                                       
                                        SAVE.onclick = function () {
                                                this.getParentForm().submitForm();
                                        };
                                </rialto:form>
