where to start Java for the web?

hi!

i am not new to Java, but I want to explore a new ground for my Java experience - the WEB.

Can anyone please provide me with links where I could study Java API's, advanced techniques (or those stuff)?

Thanks.

Do you mean you want learn how to design web applications?
try learning html, css, javascript, jsp, servlet, jdbc and any database.
you can learn html, css, javascript from W3Schools Online Web Tutorials
rest: roseindia.net

oh, i have loads of html and css, so i want to learn jsp, servlets, and jdbc..okay, gotta go to the site..

I wouldn't recommend roseindia at all.
There is useful stuff there, but there is also a lot more very bad information...and in your situation you really wouldn't be able to spot the difference.

Start with the Sun tutorials for JEE. This assumes you already understand the stuff in the base tutorials for Java.
