One must always remember that all GWT code written in Java will eventually be Javascript, and thus can only do what Javascript can do. Javascript may not wander the user's machine, looking for and opening files - even opening a file that the user has pointed you at is off limits (without the use of flash, or some other plugin).
As far as I can tell, your use-case 1 is covered by the code you have outlined, and as I have indicated, use-case 2 cannot be done by javascript alone. Instead, consider having your user select the file, using a <input type="file" />, and upload the file to the server. Then, after the upload, if the server can make it available to the user, the code you've written can download and use it, as in use-case 1. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
