Problem with FileWriter

[ADH]

Hi:

I'm writing a simple Web application that gets image data from a
third-party applet and writes it to a specified directory on a Web
server (this is done using a JSP and a JavaBean handling the file
upload.)

When I upload any *.jpg and attempt to write it to the server,
however, the size of the copied image on the server directory is
exactly the same, but when I try to open the file, I get "No Preview
Available" from Windows Picture and Fax Viewer, "Can't determine type"
from Microsoft Photo Editor, etc.

Here is the code that I used to read from the applet source and write
to the server:


try {
// get the image input from applet
ServletInputStream in = request.getInputStream();
FileOutputStream ostrm = new FileOutputStream("picture4.jpg");

byte[] readArray = new byte[1];
while((in.read(readArray)) != -1)
{
ostrm.write(readArray);
}
// close all streams
in.close();
ostrm.close();

return true;
} catch (Exception e) {
System.out.println("check console");
return false;
}

}

Can anyone help me out?

The code looks fine to me. Debug the problem by comparing the original file
to the file produced by your copy routine. Many text editors and most
operating systems have utilities that let you do file comparisons.
