My servlet read an image from the database. The type of that image that
I got from the database is InputStream
So I tried to write to the OutputStream in servlet in order to send
the data back to the applet by using the following:
response.setContentType("image/jpeg");
OutputStream out = response.getOutputStream();
byte[] buf = new byte[8000];
int n = 0;
while ((n = in.read(buf)) > 0)
{
out.write(buf, 0, n);
}
out.flush();
Then in applet, i used the following to read the returned data
In the applet:
-------------
Image img; // A member variable of the applet.
InputStream in = url.openStream(); //<----my program
died here
byte[] buf = new byte[8000];
ByteArrayOutputStream bout = new ByteArrayOutputStream(30000);
int n = 0;
while ((n = in.read(buf)) > 0)
{
bout.write(buf, 0, n);
}
bout.close();
in.close();
byte[] imageBytes = bout.toByteArray(); //by using the byte array, I should be able to create the image again
--------------------------------------------------------
However, the program was dead at InputStream in = url.openStream();
saying java.io.FileNotFoundException: http//localhost:8000/servlet/testDBServlet
where testDBServlet is the servlet that I wrote.
Anyone knows why there is such an error and how to solve it?
Thanks a million.
