Re: Trouble installing Java and Jhandles

[Khaled]

Dear Michael,

   I liked the code and it was really helpful, although it did not work, but
I learned many things.
first of all, I compiled it on a Dell Inspiron 1300 and I succeeded to
install it on Linux (OpenSuSE 10.3), but I had to do some tricks in the
configure file and the make file, for instant:

at 4231 for jhandles ver 0.3.2:
HAVE_OCTAVE_JAVA=`echo "pkg('load','java');disp('yes');" | octave -qf`
returns exactly yes, however the check at the next line (if test
"$HAVE_OCTAVE_JAVA" = "yes"; then) fails!! probably that is because the
variable  HAVE_OCTAVE_JAVA was not successfully updated. Therefore, I
changed it to some thing like hard coded yes!! and then it works and it got
the Makefile changed as well. There I removed the "-l __java__"

Afterwards, it was installed in octave. However, I got this two notes:
" Note: Some input files use or override a deprecated API.
  Note: Recompile with -Xlint:deprecation for details."

More over, there is no (*) beside the  package name, for example:

Package Name  | Version | Installation directory
--------------+---------+-----------------------
     general *|   1.0.5 | /usr/local/share/octave/packages/general-1.0.5
        java *|   1.2.3 | /usr/local/share/octave/packages/java-1.2.3
    jhandles  |   0.3.2 | /usr/local/share/octave/packages/jhandles-0.3.2

this means, that I can not recall any of the jhandles function.

I don't know what to do, may be I just need to learn how I could use the
jhandles in octave as I learned how to install it :)

I hope you could solve this problem for me

Thanks

Yours

Khaled Hassan
