For now, I've put symbolic links to jni.h and jni_md.h in /usr/include. 
 I had to manually set JAVAC and JAR in a make file, but that might be 
because I didn't have javac and jar installed at the time of configure 
but didn't want to recompile the whole lot.

I see a FindJNI.cmake on my system, if that is of any help.

I managed to run dlgtest by setting JAVA_HOME to 
/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/bin.  However, the test 
doesn't complete because the path doesn't seem correct given I built in 
a directory other than the base source tree:

octave:1> dlgtest(0)

0 ... STOP
1 ... listdlg tests
2 ... errordlg tests
3 ... warndlg tests
4 ... helpdlg tests
5 ... inputdlg tests
6 ... TeX code tests
Run which test?   [0] > 1

- test listdlg with selectionmode single. No caption, no prompt.

The file "octave.jar" is in the build directory, not the source 
directory, i.e.,

[~]# ls /usr/local/src/octave/octave/build-gui-9/scripts/java/octave.jar
/usr/local/src/octave/octave/build-gui-9/scripts/java/octave.jar

[~]# ls 
/usr/local/src/octave/octave/build-gui-9/../octave/scripts/java/octave.jar
ls: cannot access 
/usr/local/src/octave/octave/build-gui-9/../octave/scripts/java/octave.jar: 
No such file or directory

I'm guessing something is slightly off with the configuration script 
regarding the java commands.
