How deep do you want to go? Are you doing the entire Web page, or are you simply supplying data which someone else will extract to the screen? Do you have a Database Administrator (DBA)?

If you are doing it all then:

Server side:
Java - servlets, where all the real work is done
SQL - for all the database work
XML - for passing information around, and the application server web.xml file
property files - for configuration
I18N - internationalization (an I followed by 18 letters followed by an N) - This would be what the user sees.

Client side:
JSP - well OK, it is on the server, but given to the client.
XHTML
DHTML - for dynamic effects such as mouseover
CSS - for layout, colours, fonts
Javascript - for interactive support
AJAX - not the entire set (though you can), but enough to be able to communicate in the background.

There are third party Javascript tools for menus, rich text editors, spell checking (some dynamic), date pickers, pop-up boxes, and so on.

You can also look at the Google Web Toolkit ( http://code.google.com/webtoolkit/ ). You build up your screen in Java using the toolkit, then it is rendered at the client entirely using AJAX.
