sorry for x-post, but clj.help has become rather low activity.

I set up a new computer with Windows 7 64 bit and I am wondering about
which downloads I need for Java development. I need the following
components:

JavaSE
JavaEE (5)
Ant
Tomcat 6

I started by downloading JDK 32 bit, I thought it would be better to
stick with something that isn't that new. But Tomcat 6 32 bit wouldn't
let itself install as a Windows service, because it must be 64 bit
(known problem). Now the question is:

Which software do I need in which version?

JDK in 64 bit?

If you want 64 bit then download the 64 bit version.

For Java EE I couldn't find any 64 bit downloads!

That is because Java EE is pure Java. If the JVM is 64 bit then it runs
64 bit.

Does Ant work with 64 bit Java?

Yes.

Tomcat 64 bit

Tomcat itself is also pure Java.

It is only the service wrapper thingy that are 32 or 64 bit.

If you need 64 bit then download 64 bit.

The problem is Java EE, there are no 64 bit downloads.

Not a problem. See above.

Does JavaEE make a difference between 32 bit and 64 bit?

If you need more than 2 GB of memory: yes.
