Thanks again. I will try those suggestions and report back to the list. Also, I've wondered whether the space in to 'C:/Program Files (x86)/Java/...' (between Program and Files) is throwing off Octave. I'd noted the warning early on that Octave doesn't like spaces in paths- which is allowed and common in Windows and Mac directories. But I've been assuming that since it's within quotes it's OK.
More soon.
