I had a similar problem because I didn't have openJDK installed, just 
the "java" binary.  After installing the Fedora openJDK rpm and running 
Octave configure, JAVAC and JAR were properly defined.  If the 
configuration complained about not have JAVAC and JAR defined, it might 
save compiling the program then finding out there is a problem with 
"javac" and "jar" missing from the system.
