I did ignore setting the threshold and max file size before, but that didn't
result in any luck either... basically I had the following in my method body
DiskFileItemFactory factory = new DiskFileItemFactory();
factory.setRepository(new File("C:/"));
ServletFileUpload upload = new ServletFileUpload(factory);
try {
List items = upload.parseRequest(request);
Iterator iter = items.iterator();
while(iter.hasNext()) {
FileItem item = (FileItem) iter.next();
item.write(new File("test.jpg"));
}
} catch(....
The Eclipse debugger shows these variable values for the upload object:
upload= ServletFileUpload (id=1454)
fileItemFactory= DiskFileItemFactory (id=1443)
headerEncoding= null
sizeMax= -1
I also tried setting the repository location to the servlet path (and not
setting it at all) but no dice. I am running Eclipse WTP alongside Tomcat
5.5. My gut feeling is that something must be configured wrong - what are
the most basic steps that must be taken to get a single file uploaded via
the Commons Fileupload? (the documentation is rather scarce for this API).
Thanks again!

A couple of things:
1) What container are you using? Are you sure the container itself has not
already parsed the input before you try to do so?
2) You are setting the threshold and the max to the same value, so nothing
will ever be stored on disk. And then you are trying to configure a
repository on disk, which would never be used. Not sure what you're trying
to accomplish, but whatever it is, this combination doesn't make sense.
3) You are passing a bogus value to setRepository. If you want it to use a
specific directory, pass that. If you don't, don't call the method.
