How applet can be used to browse for all files in a folder without refresing the page?

I'm currently using an applet to browse for all files in a folder, but refreshing the page is still needed.

Is there an alternative process to browse for all files in a folder without refreshing the page?

Is there an alternative way to browse for all files in a folder, if I don't use an applet?

Thank you very much for your answer.

Are the files/folders on the client or on the server? Either way, why is a page refresh necessary?

The Files are on the client. Are there any ways to browse for all files in a folder,If I don't use applet?

The applet needs refresh for JSP to get the session which written by a servlet. Any advise for me? Am I doing these things properly?

Thank you for your answers.

HTML file uploads limits you to selecting a single file at a time, but you can have multiple file uploads at the same time. But you can't select folders.

Do you mean that there is data in the server session that the applet needs to access after the page has (with the applet) has been rendered? If so, why can't the applet open an URLConnection to the server that returns that value? Refreshing the page seems unnecessary and disruptive.
