How to write a text to file with GWT on Client-side?

Question

Is there any way to implement write/read file with gwt on client-side? I tried with java.io.File, java.io.Writer ... I couldn't succeed.

thx in advance!

Update: Please see my own answer for a solution

Answer 1

No, you can't write to files on the client-side. GWT only binds a subset of the Java language. Any file IO would need to happen on the server side through RPCs or some kind of web service.
