Is there a way to get the keySet from an Iterator? I am trying to implement multiple file uploads using apache commons fileupload. I need to get the filenames from all of the files selected and pass them all to add as attachments.


The below works for one attachment at a time:


But of course, I want to be able to iterate over every file selected to add as attachments.

This is actually a question on iterators rather than anything specific to file uploads or servlets, so I have moved this to the general Java forum with an appropriate change of subject.

entries.next() returns a Map.Entry<String, FileItem>. If you use a local variable for that, you can retrieve both its key and its value quite easily..
