I have a list of users I'd like to upload to a servlet to process. I've seen the HF example of how to download a jar file, but I've not been able to locate anything on how to upload a file. Is it just as simple as as using file i/o? If so, and I have my web app deployed on a remote server, how would I do this. Not looking for a solution, but a push/shove in the right direction...
The server side would be handled by a library like Apache Commons FileUpload. The client side would be an HTML form (assuming that you want to perform the upload in a browser). If the client is a Java app, it can use the Apache Commons HttpClient library.
