GWT 1.4: Getting file path for FileUpload?

[zilvonias]

Hi all!

Is there a way, client-side, to fetch the filepath for a FileUpload
widget, i.e.

1. User selects a file using the FileUpload widget.
2. GWT client requests the filename and filepath of the file selected
from the FileUpload widget.

I'm currently using GWT 1.4.61. Thanks!

There is no way to get file path from client side due to browser's security policy. You have to do it via a signed java applet or get it from your servlet.

fileUpload.getFilename should return the filename including the
absolute path. So you "only" need to separate the two parts
using indexOf and substring.

You cannot rely on getFilename to return full path of file. It depens on browser. For example, Firefox did not return full path of it.

Maybe you can achieve something accessing DOM directly. At least
the full path shows up in the text-field of the FileUpload-widget
in Firefox as well.

I discovered the same as well. Full path with IE, filename only with
Firefox.

I'll do some experiments and see if I can fetch it from the DOM.

The use case is that the user is attempting to store the filepath of a
chosen file. I thought it'd be nice to have the user use the
FileUpload to choose the file instead of manually typing the file
path. If there's another way to create a file-browsing widget and get
the file path that way, I'd consider it.

AFAIK, there's no way to do what you want with just JavaScript.
We achieve what you described with a Java Applet, saving the preferred
path on the server for each user. Of course it has the overload and
drawbacks of an applet (heavier, JRE plugin required, etc), but on the
plus side we support multiple-file uploads (including entire
directories), drag-n-drop, and uploading very large files by breaking
them into chunks.
