That means that some function (chk_spreadsheet_support.m) couldn't discern:
- a working Java environment, and/or
- a working Java package.

You say you got the latter loaded, so it appears you have no Java. You'll
need at least a JRE to be able to use the Java package.

These errors are probably related to something that is fubarred in your
Octave installation.
Perhaps you forgot to adapt the various full file paths in this file: 
    C:\Octave\share\octave\3.6.1\m\startup/octaverc
?

Not much we can do from here.
Just start searching. I'd start checking octaverc.
