Access client side filesystem


is it possible, to access resources on the client? I have formerly developed applications in Java and just startet to use my knowledge for web development with Vaadin. I have no former knowledge about web applications with Java. But I am confused, that I could not found any hint about ‘vaadin client file access’ in the www.

There is just no such thing in the web.
You can use drag&drop to upload file(s) to the server but nothing more.
It’s one of the many limitations of ANY web application.

These limitations exist for security reasons, just imagine a website could access your local drive(s) and modify/delete files…

If you need to modify the client filesystem, you could for exaple use a signed java applet which asks for the rights, but a java applet is not a well loved technology these days
