Hey!
>Please say a little more about the session objects as well.
No.
Please don't take this the wrong way, but you need to do this
research yourself, otherwise you will never understand it.
1. I suggest you get a good Java servlet book.
2. Search the web for sources of information.
3. Search this E-list archive for clues and URLs of websites that offer
tutorials.
http://archives.java.sun.com/archives/servlet-interest.html
If you have done all of this and you are stuck, then POST a specific
question, plus the error message and code snippet.
BTW, we will be able to tell if you have done your homework.
Sans adieu,
Danny Rubis
