http://wiki.apache.org/struts/StrutsFileDownload is great, but in case
you are using struts older than 1.2.6...
You just return null from execute method, framework will not do any
thing further. Now it is your responsibility to read the target file,
set correct content-type and then write the content on
response.getOutputStream();
Sample code:
public class ResponseWriterAction extends Action {
public ActionForward execute( ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
response.setContentType("application/zip");
// Set the content disposition
// To download
response.setHeader("Content-disposition",
"attachment; filename=" + fileName);
// To open up in the browser
// response.setHeader("Content-disposition",
// "inline; filename=" + fileName);
byte[] buff = new byte[4096]; // 4KB
OutputStream out = response.getOutputStream();
while (moreContent) {
// read content in buff byte[]
out.write(buff);
}
out.close();
return null;
}
}
Hope this helps.
Cheers,
Sudhaker
