OK, so the Java executables are in the PATH, which -given above commands-
implies that JAVA_HOME is set correctly.

Yeah.. where's the rest....

About the only remaining thing might be that your Java installation is
screwed up.

You've got path level 03 (1.6.0_03), I already got 33 (> 1 year old) and
AFAIK level 37 has been out for a while.
It's a good idea anyway to upgrade your Java JDK to the newest version, by
first uninstalling the current one and then installing the newer version.
Let's pray that it will solve your Java package problem.

Other than that...... I have no more suggestions... except for reinstalling
Octave.

Well that is, I have avoided spaces in various system paths: my
%Programfilesdir% = C:\Programs and where you have the IMO infinitely stupid
Windows default C:\Documents and Settings\ I simply have C:\Home\
But I never saw reports that spaces in those paths induce trouble, expect
when Octave is installed in C:\Program Files\  (you didn't, no?)
