servlet and CGI?

While doing a little research into processing forms, I ran into a new subject for me. CGI. For the most part, the articles say that using cgi scripts is the only way to process a form, but in one small little question and answer section, it said that servlets were an alternative to cgi. Does anyone know anything about this stuff? (Please tell me I don't have to learn cgi too!!)

CGI (common gateway interface) are simply programs written in languages like Perl or C that can process data from an HTML form. That is exactly what servlets are used for. If you are using servlets then you don't need to use anything else.

That is exactly what I wanted to hear!!!
I was afraid I was also going to have to learn perl in order to write these things. Thanks again!

Annette,
Just so you know. The e-mail address you provided doesn't work.

Sorry! I just fixed it. It's new, and I haven't given it out that often.

Not sure whether or not I should be starting a new thread, but...
I haven't been able to pass a value from an html form to my servlet. I've checked the error log, and it says that an exception was thrown from the servlet service function (uri=/servlet/DBInventory4).
What does this mean? What would cause an exception to be thrown here?
Annette

Well, what is in your servlet service method?

And what exception was it?

It's all good now! Turns out I needed to have a doPost method instead of a doGet. But thanks anyway!!
