How is the Java Web Start secure sandbox more flexible?
All applications, by default, are run in a sandboxed environment, similar to the Applet sandbox. However, Java Web Start provides secure APIs that allows an application to import and export files from the local disk under the users control. Thus, the APIs ex: File Save, File Open etc., are dialogs actually rendered by JavaTM Web Start, and not by the application itself. This support is not much different from what you can do with HTML. A file input field in an HTML form allows exactly the same, i.e., for the user to pick a file from the local disk, which name (excluding path) and content will be submitted to the Web server. Similar for export, most browsers support the ‘Save as…’ option.
