Java SE (Java Platform, Standard Edition)

I just installed J2EE 1.4 SDK onto a Win2000 machine. When I run a simple Java program, I get the following error message:

--------------------------------------------------------------------------------------------------------------
c:\> java Hello
Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'
has value '1.1', but '1.4' is required.
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment.
--------------------------------------------------------------------------------------------------------------

I have my path set to c:\Sun\AppServer\jdk\bin. I don't have any classpath set. Incidentally, I also have Macromedia Dreamweaver MX v 6.1 installed and it has its own JVM. Does anyone know how to fix this?

Thanks.
