Java SE (Java Platform, Standard Edition)

Hello All,
I want to get around the file upload of the html forms on to my web server.
Now since i have a signed applet which is running on the client machines, i was thinking if i can use the applets capability to upload a give hard coded file on to my webserver. I can make use of any servlet/jsp if needed in order to handle the request on the server side. But am not sure where do i start from in order to upload a file from applet to the webserver.
Can someone provide me a jump start on this.


Thanks,
