[Java-gnome-developer] bug or missconfigured

[Antonio R. <ant...@gm...>]

What does this log mean? I'm on Ubuntu and I cannot if I need some
more packages.

The code is the simple glade loader from the javadoc.

Why are you blanking java.library.path? It needs to be
$whatever_directory_libgtkjni.so_is_in. The README file available in the
sources and at http://java-gnome.sourceforge.net/4.0/README.html is
pretty clear about that.

oh no, this is a stupid error in my email. In my launch code I use

-Djava.library.path=/usr/lib

but your email make me check if libgtkjni.so exist; in /usr/lib there
is only libgtkjni-4.0.so

:/usr/lib$ ls libgtkjni*
libgtkjni-4.0.so

so I linked it to libgtkjni.so but this seem to not affect my error.

No no, that's right, and that's what the library loads. Anyway, /usr/lib
is on the implicit LD_LIBRARY_PATH, so you shouldn't even have to
specify it. I was just concerned that you were setting it to "".

Don't do that.

Incidentally, the attempt to load Calendar stuff is a glitch, and I
filed a bug for it. That's got nothing to do with this problem, though -
you're going to link to the native library sooner or later. Your Java VM
isn't finding native libraries, and that's the problem that needs
resolving.

Why don't you come join us in #java-gnome and we'll discuss it further
there.

 Hi,
can it be that you have forgot to call Gtk.init() before you do some
java-gnome specific things? This happened to me a few minutes ago while
trying to implement the FileChooserDialog:-P

Regards,
Thomas.

I clued in that this was the case myself a few weeks back.=20

I just put in a check in org.gnome.glib.Plumbing's static block to make
sure Gtk.init() has been called, and to crash out if it hasn't been.
This is a bit thuggish, but it'll do for now until (and unless) we
implement this differently [it's fine the way it is; there's more to it
than just moving the System.loadLibrary()]

Anyway, people who forget to initialize GTK will no longer get the
confusing stack trace about GtkCalendar or whatever.

[Note that the bug about over-jealous class loading is still extant]
