Diagnosis:
the call to (compiled) function java_invoke() doesn't work. (That function
lives in java.oct. Is there a java.oct in
/usr/<local/>libexec/octave/packages/java-1.2.8 or its subdirs?)
I suspect the java package simply didn't get installed properly. This is
usually caused by java configuration problems - did you try
I check both OpenJDK and Sun JDK installation on FC11.
Both installation placed libjvm.so on the server directory, not the
client directory.
I believe this is the default behavio on FC11.

I think the Java pkg installation works as long as I create the client
sym link to point to the server directory on FC11.
That's the only thing I had to.
My previous issue with dlgtet() was caused by the fact that I tried to
run it as a root without X11 forwarding (I didn't know the test was
generating a gui window).
The dlgtest and javamem functions worked fine but javaclasspath
function failed as shown below.

So,
1. The Java package generally installs & works OK. Good.
2. javaclasspath:
That's funny, the wrong argument order to java_invoke inside it was one
of the things I thought I'd fixed. I'll check again in svn.
Attached is a fixed javaclasspath.m, please put in place of the one in
/usr/local/share/octave/packages/java-1.2.8
(if you installed the java package as root I think it can be found
there. Otherwise you'll have to look around in your home dir.)
(BTW If you are curious you can compare the files around line 53)
Please report back if all works OK after this last fix.
Anyway, thank you very much for helping to check the Java package.
Best wishes,
Philip
