Java package install seems to be ok, but is NOT working.

[Herdon]

I have Windows XP sp3 32 bit and Octave 3.6.2 gcc4.6.2.
I downloaded package java-1.2.9.tar.gz and managed to install it after
playing with JAVA_HOME variable.

Command pkg list shows that java is installed, and I issued command pkg load
java, but after that java commands does not seem to be working.
What happens is like this:
octave:3> v = javaObject ("java.util.Vector")
warning: the `javaObject' function is not yet implemented in Octave

octave:3> javamem
error: `java_invoke' undefined near line 65 column 8
error: called from:
error: C:\Program
Files\Octave362\Octave3.6.2_gcc4.6.2\share\octave\packages\java-1.2.9\javamem.m
at line 65, column 6

So, what might be the problem?

Hi Heron,
have you installed the octave-forge packages as described in the README?
See
http://sourceforge.net/projects/octave/files/Octave%20Windows%20binaries/Octave%203.6.2%20for%20Windows%20MinGW%20installer/
Chapter 3. Manual installation instructions for the Octave-forge packages

I've installed octave3.6.2_gcc4.6.2 and Octave3.6.2_gcc4.6.2_pkgs_20120613.7z as
described in the README on a WindowsXP Pro 32bit
(don't forget the pkg rebuild steps) and the java packages works like a charm:
octave:1> v = javaObject ("java.util.Vector")
v =
<Java object: java.util.Vector>
octave:2> javamem
Java virtual machine (JVM) memory info:
Maximum available memory: 63 MiB;
(...running garbage collector...)
OK, current status:
Total memory in virtual machine: 4 MiB;
Free memory in virtual machine: 4 MiB;
4 CPUs available.

The problem is that the package hasn't been installed properly.

On Windows the issue is that not only JAVA_HOME must be set, but also the
Java JDK executables (javac.exe (Java compiler), jar.exe (Java archiver))
must be in the PATH. If you would have added the -verbose flag to the pkg.m
command you would have seen something like "Java: no" somewhere in the
build messages.

So before another retry to install the Java package, add the subdirectory

%JAVA_HOME%\bin

to the PATH and try again.

FYI: this *IS* outlined on the wiki:
http://wiki.octave.org/Java_package#Make_sure_that_the_build_environment_is_configured_properly

Hello,

I'm having the same problem as Herdon. I installed the java package as per
the instructions on the wiki link Philip posted. The installation seems to
work but the javaObject error persists when I run the test code on the wiki
page ("warning: the `javaObject' function is not yet implemented in Octave
"). I get the same error for several other functions in the java package
(java_invoke, java_exit, etc.) When I look in the folder where the package
was installed, "C:\Program Files
(x86)\Octave-3.6.2\share\octave\packages\java-1.2.9," some of the functions
that were listed on the Octave-Forge website,
http://octave.sourceforge.net/java/overview.html, are missing. These
functions include those, such as javaObject, that produced an error. Might
this be a the source of the problem? If not, any other solutions would be
appreciated. Thanks!

Brian

Did you load the Java package after installation?
pkg load java

If you did and some Java functions are still lacking, the package is simply
mis-installed.

I don't know how you installed the Java package; what I would do is more or
less along these lines:

1. Check Windows PATH for the <JAVA_HOME>\bin directory
(In my case this is an entry like
.....;C:\Programs\Java\jdk1.6.0_33\bin;....... where ..... stands for rest
of PATH entries); in your case it might be something like ...;C:\Program
Files (X86)\Java\bin;.... )
Note that you might need a 32-bit version of the Java JDK. I'm unsure about
that, I can't check that on my remote 64bit work box now as I cannot login
from Linux lately.
Note also that 64-bit Java versions may have the jvm.dll in .../server, not
.../client. AFAIU this is only relevant on Linux, but again I'm not sure.

2. In a cmd32.exe terminal, do "javac -version" (without double quotes).
You should get a response from the Java compiler, echoeing its version
number. If not, fix step 1. above

3. Start up Octave, do
setenv ("JAVA_HOME", "/full/path/to/Java-JDK/WITH/FORWARD/SLASHES")

4. Switch off the pager, so that you can copy all messages into an email if
needed:
more off

5. In Octave install the Java package:
pkg install -forge -verbose java
(this will install from Octave-Forge and give some more feedback on the
build process)

6. Check the build messages for a line saying "Java....: yes" (scroll back
if needed)
If you see something like "Java....: not found" your JAVA_HOME setting is
wrong; fix it in step 3.

The java-1.2.9 package features a file called preinstall.m which should
check for (and as far as possible fix) most of the above issues. If it
doesn't complain I wouldn't know how to fix your problems without a more
detailed report containing:
- Your JAVA_HOME setting (preferrably echoed from Octave: getenv
("JAVA_HOME")
- Your Windows PATH
- The output of
javac -version
from a cmd32.exe window
- The output (messages) from the pkg install command (see steps 4/5/6)

I'm afraid this is about all I can do to help out.

Philip

I removed old java installation, and restarted Octave.

PATH has all the time contained this (only java related item in my PATH):
C:\Program Files\Java\jdk1.6.0_03\bin;

In command prompt:
C:\>javac -version
javac 1.6.0_03

Then in octave:
octave:1> setenv ("JAVA_HOME", "C:/Program Files/Java/jdk1.6.0_03/")
octave:2> system ('javac -version 2> nul')
ans = 0
octave:3> more off
octave:4> pkg install -forge -verbose java
mkdir (C:\DOCUME~1\LOCALA~1\LOCALS~1\Temp\oct-2)
untar (C:\Documents and Settings\localadmin\java-1.2.9.tar.gz,
C:\DOCUME~1\LOCALA~1\LOCALS~1\Temp\oct-2)
For information about changes from previous versions of the java package,
run 'news ("java")'.
octave:5> s = javaObject ("java.lang.String", "Hello OctaveString")
warning: the `javaObject' function is not yet implemented in Octave

Please read `http://www.octave.org/missing.html' to learn how you can
contribute missing functionality.


error: `javaObject' undefined near line 5 column 5

Then I realized I did not load the package, but it did not help:
octave:5> pkg load java
octave:6> s = javaObject ("java.lang.String", "Hello OctaveString")
warning: the `javaObject' function is not yet implemented in Octave

Please read `http://www.octave.org/missing.html' to learn how you can

error: `javaObject' undefined near line 6 column 5


So, in principle, everything seems to be ok, but nothing is working. Any
more ideas?

I checked on my 64-bit Win7 box at work. I have both the 64-bit and 32-bit
version of the Java JDK installed (both seem to work BTW), and I've probably
used the 32-bit version to build the Java package, the one in (on that box)
C:\Program Files (X86)\Java\jdk1.7.0_07

So my advice is -again, assuming you run Win7 64-bit- to also install a
32-bit JDK and use that in JAVA_HOME and PATH to build the Java package.

My system is Windows XP sp3, 32 bit.

My previous posting contained all messages Octave gave, copied directly from
prompt, and pasted here. There was absolutely nothing more.

BUT, I have to say that I have NOT compiled anything, but installed Octave
from the ready made package from here:

Very intruiging.
Does your Octave installation have deviating write permissions?

Another possibility may be that the old Java package wasn't completely
removed because it was in use (might be because some Java class libs (.jar)
have been loaded while starting Octave, in that case some shared libs may be
in memory blocking removal of those library files on disk).

What you can do is some advanced but ugly surgery (tested on my local
Octave-3.6.2-gcc4.6.2 installation, WinXP SP3 like you):

-----start Octave & uninstall Java package:-----
pkg unload java
pkg uninstall java

-----quit Octave-----
----- Now, in the octave directory, go to
1. lib/octave/packages/
2. share/octave/packages/
and manually wipe any remaining java directories there ----

----- start Octave and clean up package list-----
pkg rebuild

----- quit Octave, and start Octave again. Check that no Java package is
installed:-----
pkg list

----- Prepare JAVA_HOME & PATH (note: locations & version may obviously
differ) + do some checks:-----

octave:2> setenv ("JAVA_HOME", "c:/programs/java/jdk1.6.0_33")

Somehow it seems that pkg install command does not do very much, because
there is only two lines of resulting information after that. In your example
there was much much more!

Could it be that I should have never Java installed, or maybe there is just
something wrong with my computer?

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

Somehow it seems that pkg install command does not do very much, because
there is only two lines of resulting information after that. In your
example there was much much more!
Could it be that I should have never Java installed, or maybe there is
just something wrong with my computer?

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?)

I am neither Octave no Windows developer.

The first error message is
"
java: Java Development Kit not found
".

And above I see:
"
[1,24] = C:/Program Files/Java/jdk1.7.0_13/bin
".

Well, the rule of thumb is to avoid whitespaces in paths - because shells and whitespaces are not friends - whitespace are used as characters to split on.

So I would first uninstall Java and reinstall it in a manner there are no whitespaces in the paths, e.g. create

C:\MySpecialJava

folder and install Java into it.

Regards,
Sergei.

[Werner]

Hell List,

Sergei is right at all. I have had the same problems and my assumption was
exactly like Sergei's
So I decided to make a new java installation (the current installations was
in any event old - jdk1.6.0_31)
My system is windows 7 and so the installation was in c:\Program Files\Java
... Keep in mind the
whitespace in path. With this settings you get an error, when you install
java with
pkg install -verbose java-1.2.9.tar.gz. You have carefully check the
output, there is the message that
the make file can't found c:\Program Files\Java ... So I install the new jdk
(jdk1.7.0_25), but in the
installation process I "correct" the path from c:\Program Files to
c:\ProgramFiles (it's a little bit strange
for a windows 7 system). Therefor my output from strsplit (getenv("PATH"),
pathsep) contains now
[1,7] = c:\ProgramFiles\Java\jdk1.7.0_25\bin\ and that was what I wanted ->
no whitespace in the path.
When you now install java with pkg, then all is correct.

So long Werner

Another issue I hit is that on my 64-bit Win7 box at work, Octave (32-bit)
doesn't like the 64-bit JavaJDK; not even with the trick of copying the
./server/ directory to the ./client/ directory (the Java package expects
jvm.dll to be in ....../client)

I explicitly had to wipe the 64-bit JDK and install a 32-bit JDK. It doesn't
matter that the latter is somewhere in C:\Program Files (X86)\ (enough
spaces, isn't it?).

My experience on Windows is that it is vital for Octave itself to be
installed in a path w/o spaces. But support SW (Java, Ghostscript, etc) in
e.g., C:\Program Files\ is often recognized properly by Octave. Mind you:
YMMV.

Philip
