JSP file i/o

Hi
How is it possible to load files from a users harddrive using jsp?

Not at all. Security nightmare.
You can create a file upload form.

I have been searching google for hours, and I have found very complex jsp implementations of it. But I only wan't something simple. I text field to contain the path, a browse button and an upload button. Do you have an example?

Try http://jakarta.apache.org/ , specifically the commons-fileupload component. It's the simplest file upload thing I've seen so far in Servlets.
