CGI Tutor

This essay is about a suggested student project in Java programming. This essay gives a rough overview of how it might work. It does not describe an actual complete program. I have no source, object, specifications, file layouts or anything else useful to implementing this project. Everything I have to say to help you with this project is written below. I am not prepared to help you implement it; I have too many other projects of my own.

I do contract work for a living, which could include writing a program such as this. However, I don’t do people’s homework for them. That just robs them of an education.

You have my full permission to implement this project any way you please.

This is a very simple echoing tool to help you understand CGI messages. Instead of directing the data from a form to the standard CGI server, you direct it to one running the cgitutor.

It echoes it back in three forms:

Raw, exactly as it arrived.
Decoded, turning punctuation and control chars back to normal form.
Parsed, into keyword="value" pairs.

The Center for the Study of Art and Technology National Institute of the Arts in Taiwan offers a debugging tool that provides the parsed format (3) only.

1250 pages. This is a great doorstop of a book. It has a few chapters on client-server programming in Java, and a section of that is on CGI. I have looked at hundreds of Java books and found nothing that deals in depth with client side Java talking to CGI, except Marty’s book. It is really very simple and he does an excellent job of explaining it. Marty has posted all the source code examples from the book for anyone to use. These contain updates and errata fixes you don’t get on the CD-ROM that comes with the book.

explains how to do this. It is a very easy project. All you need is a server somewhere to run the code on.

You could turn this into a commercial project by showing ads along with the other info.
