This must be about the worst advice I have ever seen.
What about someone typing e.g. "/etc/passwd" in that text box?
If you allow people to upload files to your server, you should create your own location
and naming scheme for the uploaded files. You should not even use the original filename,
unless you are dying to experience all the silly things that people can think of in terms
of filenames (with spaces in them, or characters that are valid on one platform but not
another, or characters in various character sets and so on.)

You need to add a line in in your form:
<input type="text" name="filename" />
Then in your servlet GetPost() method you put this filename in a variable:
String filename;
filename = req.getParameter("filename");
Then instead of part.write("samplefile");
do:
part.write(filename);

Subject: Servlet 3.0 File Upload
Hi,
I have a working file upload servlet, with the exception that it calls the uploaded file
"samplefile" instead of using the name of the file. So if I upload different
files, they all overwrite each other. Any ideas on how to fix this? I used this
tutorial to get it working:

TIA,
- Ole
