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
Recently, I've stumbled upon a library called client-io.
A simple library that brings the Flash File API to regular web apps through GWT. ClientIO will help you offload some of the file generation functionalities to the client, saving resources and heavy computation to the server. Working Demo - http://ahome-it.github.io/ahome-client-io/
