This is possible to do fairly easily, here's some sample code:
FacesContext facesContext = Utils.getFacesContext();
HttpServletResponse response = (HttpServletResponse) facesContext
.getExternalContext().getResponse();
try {
response.setContentType(attachment.getContentType());
response.setHeader("Content-disposition", "inline;filename="
+ attachment.getName());
response.getOutputStream().write(attachment.getDocument());
}
catch (IOException e) {
System.out.println(e);
}
facesContext.responseComplete();
The above code is in a utility we can call anywhere we need it, but it's called
by an action when a user chooses to view an attachment.
Our Attachment object has the following methods:
String getContentType()
String getName()
byte[] getDocument();
You could do something similar using Poi (to generate and output a spreadsheet).

Subject: FileDownload capability?
We have an application requirement saying that the user needs the ability to
push a button on our report page to download the report data into a local file
on the user's machine suitable for loading into a spreadsheet. How can
something like this be done?
