Hi all,

I am trying to export an excel sheet in GWT. When ever the user clicks on the Download button, a dialogue box should pop up asking the location to save the file and when the user hits submit button, an excel file should be downloaded to that location.

I am able to generate the excel sheet but i am not clear on how to show the pop up dialogue box.

Can any one help me on this problem please.

Thanks

To force download dialog box to appear all you need is to set the "Content-disposition" to "attachment". It's nothing much to do with GWT.
For more information google the keyword "force download html".

In my servlet I use this to create pdf report and send to user.

ServletOutputStream out = response.getOutputStream();
byte[] reporte = JasperExportManager.exportReportToPdf(jasperPrint);
response.setContentType("application/pdf");
response.setContentLength(reporte.length);
response.addHeader("content-disposition", "attachment; filename=\""+ reportFileName + "\"");
out.write(reporte, 0, reporte.length);
out.flush();

Harsha, how can I generate the excel sheet ?
