Hello,
I have developed a new library to address the problem of loading files
which are on the local filesystem of the end-user into GWT
applications. Actually the library is just a simple GWT wrapper for
the W3C file API and some parts of the HTML5 drag and drop API. If you
are developing an application where you want your users to open files
on their local filesystem without having to upload them to a server
first, this might be of interest to you.

The lib is published under LGPLv3.

More details can be obtained here:
http://www.vectomatic.org/google-web-toolkit/a-file-api-for-gwt
The lib itself is available here:
http://code.google.com/p/lib-gwt-file/
A demo is also available here:
http://www.vectomatic.org/gwt/lib-gwt-file-test/lib-gwt-file-test.html

Regards,

Lukas

Hi Alain,

Yes, if you know the format of PDF or Excel, you can process such
files. The API offers a byte-level API (more or less equivalent to
what you have with a java.io.InputStream). Mozilla has a demo where
they show how they are able to process EXIF metadata in jpeg pictures
