How to set up a Java EE development environment

I want to set up a Java EE dev environment, and so I downloaded
Java Platform, Enterprise Edition 6 SDK Update 3 (with JDK 7).

When I try to install it, I get the message:
Error: Could not find the required version of the Java(TM) 2 Runtime Environment in 'null'.

There are no options/wizard.

if I type in java -version at the command prompt, I get:
java version "1.6.0_20", which came pre-installed on my Windows 64-Bit machine.

if I type in javac -version at the command prompt, it doens't recognise it. (I suppose javac is not installed.)

What do I need to do?

Thanks

Download Netbeans for Java EE developers. Comes packed with Tomcat and Glassfish as well which is very handy.

Welcome to the Ranch

How did you set your PATH? Start with this FAQ.

@ Alan Smith:
Thanks for the suggestion.
However, it doesn't come with Java itself does it?

@ Campbell Ritchie:
Thanks!
It seems that FAQ sets paths to the JDK installation after its installed.
I can't even install it.
I click the download, and it starts installing, but then shows the error message.
Am I using the wrong install file?
Can I set paths before installing?
Should I reinstall the JRE?
Do I need javac installed?

I ask all of this because I really don't know where to start.

Thanks again.

Welcome to the Ranch (if you haven’t been welcomed already).
No, don’t install the JRE; you don’t need that, because all its components are already in the JDK.
It can do no harm to reinstall the JDK; you might as well use JDK7u3. That includes javac.
Have a look at this thread and see whether there is anything useful there (there might be nothing useful for you).
I presume you have administrator privileges, etc etc.
What sort of error messages are you getting when you try installation?

Sorry I can’t help any more at present.

@ Campbell Ritchie:
The link you provided to JDK7u3....is that for the Enterprise Edition jdk?
I need EE.
Thanks

No, that was the standard edition. I suggest you get that working before upgrading to EE.

Someone suggested to me that it might be because of the Windows version I'm using
Lo and behold, its Windows 7 Home Premium.
Could that really be?
@Campbell Ritchie: I'll try SE first.
Thanks
