Transfer a file using a servlet
I need to transfer a file from a users PC to our application/web server and have that file associate with the record they are editing.
I've begun with the following HTML:
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title></title>
</head>
<body>
<form method="POST" action="http://localhost:8080/rpswq/UploadTest" name="ProcessAccountForm"">
<input type=file name="filetoload">
<input type="submit">
</form>
</body>
</html>
In my servlet, I can get the file name from the request (req) but I do not know how to proceed. I've tried copying the file from the filename to the destination machin, but the filename is always "C:\somehtin\file.ext" and that does not exist on the server so it errors out.
Can anyone provide some guidance here? I am very lost.
Thanks!
Servlet code:

import javax.servlet.http.*;
