How: reading from client and writing to server

[Croven]

Hi,

Currently, I am writing a java servlet program and
I encountered the following problems:

How can I read and write a image file "*.gif" from the
client's harddisk to server's harddisk when the user post
the HTML parameters to the java servlet?

It's not clear what you mean here because servlets don't have clients. Do
you have HTML that sends the _name_ of a file to the servlet? You can't do
anything with that because the servlet doesn't know what computer the
request came from. Or do you have an applet that's sending a request to
your servlet? Probably the same problem, plus applets can't get at files on
the client's disk either without security precautions such as applet
signing.

By the way, HTML has a "Put" (as opposed to the usual "Get" or "Post")
method. I've never seen it used and most servers disable it (and I don't
exactly know what it's supposed to do) but you could look into that.
