Unfortunately that is what I do
OutputStream dos = null;
FileInputStream fis = null;
try
{
fis = new FileInputStream(rf.getPdf());
response.setContentType("application/pdf");
response.setContentLength((int) rf.getPdf().length());
//response.setHeader(response.)
dos = response.getOutputStream();
int read = -1;
byte[] bytes = new byte[100000];
while((read = fis.read(bytes)) != -1)
dos.write(bytes, 0, read);
dos.flush();
return mapping.findForward("PDF");
} catch (Exception e)
{
// TODO Auto-generated catch block
if(e instanceof SocketException)
return mapping.findForward("reload");
throw new IOException(e.toString());
}
finally
{
if(dos != null)
dos.close();
if(fis != null)
fis.close();
}
Acrobat now loads but the PDF doesn't appear.
Probably worth mentioning that I use struts, so I forward to a blank page
with the content type set to application/pdf, maybe that is the problem, but
not sure what else to do with the return.
When I do the same thing with a dynamic image and forward to a page with a
jpg content type, the image appears without a problem.
