Upgrading from 1.4 to 6 - some code doesn't compile.

Question

Hi all, I've just upgraded from version 1.4 to 6. I tried compiling a few classes and I'm getting errors (it previously compiled fine under 1.4).
Any idea how I can get the errors below fixed?
I've checked the version 6 api and it doesn't contain the servlet classes that I require:
import javax.servlet.http.*;
import javax.servlet.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
Here's a few errors:

Answer 1

Can you please show me exactly what I need? I've tried downloading a couple of things:
Java EE SDK 5 Update 2 No JDK
and
Java EE 5 SDK Update 2 (with JDK)
Both times I got an application server installed and I couldn't use Tomcat.
I thought this would be easy to sort out. What exactly do i need to do?
Cheers again,
MM
