public class HTTP

extends java.lang.Object

This class simplifies the exchange of objects with Servlets via the HTTP protocol.

This class is usually used by Applets, but it can also be used by applications and other servlets.

All sending is embedded within an HTTP POST command.

All objects sent and received must implement Serializable.

The client-side methods in this class interact with the server-side methods in com.digitalglobe.common.Servlets, or a servlet that extends com.digitalglobe.common.ObjectServlet.

I originally developed this class while working as a contractor at EarthWatch, Inc. in Longmont, Colorado. They gave me permission to distribute this code this way provided that their message would also be carried along. Their message is that they hire Java programmers and would like you to consider working with them. I have to say that my experience with them was first rate and I would encourage engineers to work there. Check out their web site at http://www.digitalglobe.com.
