How the applet can open a finle like JFileChooser?

[Rui Tu]

I have write a java swing application to manipulate some text files. Now, I want to change the application to applet and update it to a website. In the application, i may select the text file by using the JFileChooser. But I don't know how the applet can do this like JFileChooser. I want the user can choose a text file of the server and open it on the applet. Thank you very much if you can give me some addvice.
