about upload applet

I'm Mauro Landro, working for Progesi
In the file below there is a java class for Put method with http protocol.

unfortunately I don't know where to find and how to compile or use the following packages:
www.w3c.mime.* , www.w3c.http.* ,
www.w3c.protocol.http.*.

can anybody help me?

thank you very much, best reguards
