The piece of code at the bottom of this Google Answers post helped me out a LOT: It showed a way of uploading files chunked into smaller bits, so you can easily use a JProgressBar. Setup to be installed on client device may be downloaded from Ive had to do just this, with very large (4Gb+) files.
JFileUpload supports very large uploads over 2GB and could resume broken upload. Front-end provides an upload progress bar, a cancel button and drag&drop support. It is suitable for any OS installed on a client’s computer. Most users has Java installed (the quantity of such users is growing), also JRE can be easily downloaded and installed automatically within 1-2 minutes.

Without these, your signed applet runs without restrictions and could be run from any website (depending on the version of Java used). When creating a JAR file for signed code, you will need to add some manifest entries to it.
HttpURLConnection theUrlConnection = (HttpURLConnection) url.openConnection() Java code must be packaged in a JAR file (including applets), in order to be signed. Public void upload(URL url, List files) throws Exception Private static final String Boundary = "-7d021a37605f0" Basically, I think the code in your question is missing some parts that the HTTP protocol requires public class UploaderExample Here is some code that might help you it's from one of my old projects with a bunch of unrelated stuff removed, take it for what it's worth.
