...which -assuming you run Win7 64-bit- is the 64-bit version of the JDK.

...also pointing to the 64-bit version.

Where is the rest of the messages? I'd expect some 4-5 screens of messages,
not just those 2 lines....

I checked on my 64-bit Win7 box at work. I have both the 64-bit and 32-bit
version of the Java JDK installed (both seem to work BTW), and I've probably
used the 32-bit version to build the Java package, the one in (on that box)
C:\Program Files (X86)\Java\jdk1.7.0_07

So my advice is -again, assuming you run Win7 64-bit- to also install a
32-bit JDK and use that in JAVA_HOME and PATH to build the Java package.
