Thanks Jason
I'm having a strange issue with serving up these images. I'm getting a "socket
write
error" from the following code. There are 3 images, the details follow the
code. The
first two images appear, the third fails to appear.
response.setContentLength((int) f.length());
response.setContentType("application/x-file-download");
response.setHeader("Content-disposition", "attachment;
filename=" + name );
System.err.println(">> " + response.toString());
FileInputStream fis = new FileInputStream(f);
ServletOutputStream sos = response.getOutputStream();
byte[] buffer = new byte[32768];
int n = 0;
int x = 0;
while ((n = fis.read(buffer)) != -1) {
System.err.println(">> x = " + x++ + " n = " + n);
sos.write(buffer, 0, n);
}
fis.close();
sos.flush();
} catch (Exception e) {
System.err.println(">> Error serving image: " +
request.getParameter("local"));
e.printStackTrace();
}
Image 1 bytes: 7734
Image 2 bytes: 79279
Image 3 bytes: 2871052 (image called "2_another quite night on tour.tif")
The generated log file:
