JSP vs ASP

[Mindy Wu]

Hello there,
I've been learning java for about 3 months and now I know how to do many basic stuff with it. However, I never know what is JSP, and i really want to learn it too. It is my first time to post a question in JSP forum, so thanks for your welcome. I have ASP(Active Server Page), visual basic language background and I am wondering which language has more advantage, and some differences between them. If I want to learn JSP where should I start?
Thanks! Thans! for your advice.
Mindy
