Hi, Thanks! Seems that the following code works, but
after the call to the lister method is finished the
Tapestry framework throws a lot of exceptions .. see
below.
Does anyone have an idea how to overcome this?
=====================================================
FileInputStream in = new
FileInputStream(file);
response.setHeader("Content-disposition",
"inline; filename=" + file.getName());
response.setContentType(mimetype);
response.setContentLength((int)size);
ServletOutputStream out =
response.getOutputStream();
while (in.read(data) > -1) {
out.write(data);
}
in.close();
response.flushBuffer();
=====================================================
