One area of confusion in EAR/WAR creation is that the user indicates the file to upload but also has to enter a package name. One reason is flexibility; the user can indicate a destination file name that is different than the uploaded file. Admittedly, that's probably a rare use case; I don't believe I figured out how to extract the file name from the upload component when I first wrote this. For ease of use though, we can eliminate the package name field and determine it from the upload field.
