Hi,

I had the same problem some time ago because the name has changed, it should
be -lgtkjava-2.6 and -lgladejava2.8

[Java-gnome-developer] How to compile native with gcj

[Luca M. <luc...@ti...>]

Hi,
I'm trying to compile a sample program natively with gcj but I got this
annoying message:

make native
gcj
-classpath /usr/share/libgtk-java-2.6/lib/gtk2.6.jar:/usr/share/java-gnome/=
lib/glade2.8.jar -lgtkjar2.6 -lgnomejar2.8  --main=3Dcom.osnetwork.Main -o =
bin/jquote src/com/osnetwork/Main.java
/usr/lib/gcc/i686-pc-linux-gnu/3.4.3/../../../../i686-pc-linux-gnu/bin/ld: =
cannot find -lgtkjar2.6
collect2: ld returned 1 exit status
make: *** [native] Error 1

I have used the Makefile from java-gnome website made by NickG, I just
changed this variables:

INCLUDES=3D/usr/share/libgtk-java-2.6/lib/gtk2.6.jar:/usr/share/java-gnome/=
lib/glade2.8.jar
LIBS=3D-lgtkjar2.6 -lgladejar2.8=20
LIBPATH=3D/usr/lib
FILES=3Dsrc/com/osnetwork/Main.java
MAIN=3Dcom.osnetwork.Main
TARGET=3Dbin/jquote

How can I solve this?
Thanks in advance

Re: [Java-gnome-developer] error: java.lang.reflect.InvocationTargetException: ListenerDelegate.create failure

[Joao V. <jvi...@ya...>]

Actually... don't search for that part in the file... (i've got a feeling you won't find that
part)... try searching for this part:

} catch (Exception e) {
   throw new InvocationTargetException(e, "ListenerDelegate.create failure");
}

and replace it with:

} catch (Exception e) {
   e.printStackTrace();
   throw new InvocationTargetException(e, "ListenerDelegate.create failure");
}

Thanks,

Re: [Java-gnome-developer] error: java.lang.reflect.InvocationTargetException: ListenerDelegate.create failure

[Joao V. <jvi...@ya...>]

Still that bug... :/

Hey Leonardo, the version of libglade-java you're using, did you build it from sources or did you
install it from some rpm/deb package? Because i would like you to try something, to help us find
what's the bug exactly...

(The problem we're having is that most of us can't reproduce this bug... and the message
"ListenerDelegate.create failure" doesn't tell us much... so we need more info from the ppl who
can reproduce it)

... here's what i'd like you to do: get the source of the version you're using, open the file
'src/java/org/gnu/glade/ListenerDelegate.java' in an editor, and search for this part of the file:

} catch (InvocationTargetException e) {
            System.err.println("ListenerDelegate.fireEvent("+event+"): "+ 
                               e.getTargetException());
}

When you find it, replace it with this:

} catch (InvocationTargetException e) {
            System.err.println("ListenerDelegate.fireEvent("+event+"): "+ 
                               e.getTargetException());
            e.getTargetException().printStackTrace();
}

Now compile/build/install libglade-java, and try it. If you get the same error (i hope you do!),
now you'll probably see more error msgs. So post them to us!

Thanks,
J.V.

[Java-gnome-developer] cvs changes

[Jeff M. <ku...@gm...>]

This morning our java-gnome project in gnome cvs was split into nine separate
toplevel modules.  This change was made to more accurately reflect the
individual
projects with their individual release schedules.  All projects still
fall under the
Java-GNOME project - just cvs access has changed.  To learn how to get the
code from cvs you can go to our GetJavaGnome page on the wiki.

[Java-gnome-developer] libgtk-java update

[Jeff M. <ku...@gm...>]

I will be releasing version 2.6.1 of libgtk-java next Wednesday.  At that
point two significant events will occur.  First of all libgtk-java will be
moving into its own project in cvs.  Secondly I will be creating the
maintenance branch for continued 2.6.x support.  This means that
cvs head will become our development area where we will work
towards our libgtk-java 2.8 release.

The only insight on the specific crash you're encountering is that most
people tend to use the LibGlade constructor with "this" to specify where
the signals are going and what not [though, I've come to realize that
it's generally more powerful (though not as easy) to use java-gnome
listener/event pairs]. Maybe passing your "InputEditLogic" instance is
the problem.

For what it's worth, I've been addressing this sort of issue by 
a) naming my classes as WhateverWindow, and b) having the libglade call
just be a part of the constructor for WhateverWindow, and saving the
returned object in an instance variable. eg:

private LibGlade	_glade = null;

WhateverWindow() {
	try {
		_glade = new LibGlade("share/whatever.glade", this);
...


<shrug> Works for me; an instance field seems an appropriate place for
it, and it saves having to code up the singleton pattern.

[Java-gnome-developer] Possible error in LibGlade.java

[Clint A. <ca...@au...>]

This could just be me doing something wrong, but I've got a strange
problem here.  I've got some singleton classes which extend LibGlade.  As
part of my testing, I'm instantiating them when the Glade XML data file
doesn't exist, so they should throw FileNotFoundException or the like. 
And they do, the FIRST time.  The second time, the entire JVM crashes,
leaving a big trace file (I attached one for ya'll to look at).
Here's an example of the code in question:

public final class InputEditGlade
extends LibGlade
{
    /* The Glade data file (doesn't exist, so constructor should throw
     * an exception).
     */
    private static final String GLADE_FILE = "glade/inputedit.glade";
    // The singleton instance.
    private static InputEditGlade _instance = null;

    // Singleton constructor.
    private InputEditGlade()
    throws GladeXMLException, FileNotFoundException, IOException
    {
        super(GLADE_FILE, new InputEditLogic());
    }

    /**
     * @return
     * The singleton instance of this class.
     */
    public static InputEditGlade getInstance()
    {
        if (_instance == null)
        {
            try
            {
                _instance = new InputEditGlade();
            }
            catch (final GladeXMLException e)
            {
                Notifier.getInstance().exception(e,
                        "An exception occurred " +
                        "while trying to parse the Input/Edit Glade " +
                        "file.", Level.ERROR);
            }
            catch (final FileNotFoundException e)
            {
                Notifier.getInstance().exception(e,
                        "The input/edit Glade"+
                        " file could not be found.", Level.ERROR);
            }
            catch (final IOException e)
            {
                Notifier.getInstance().exception(e,
                        "An I/O exception occurred " +
                        "while trying to read the Input/Edit Glade " +
                        "file.", Level.ERROR);
            }
            catch (final Exception e)
            {
                Notifier.getInstance().exception(e,
                        "An unknown exception occurred while trying" +
                        " to load the Glade file.", Level.ERROR);
            }
        }
        return _instance;
    }
}

The first time through, the constructor properly throws an exception.  The
second time through is when the crash happens.  I've looked at the source
for the LibGlade class, as well as the libglade C sources, and I can't
figure this one out.  Any ideas?

Andrew, in the context of Java-Gnome there's really nothing the Sun's VM can do that GCJ/Kaffe
can't do, really. I know you know that, because you said this yourself in the email. So Sun's VM
is not a solution, because GCJ/Kaffe is not the problem here.

As for being "pro-GCJ", here goes my opinion (which is not necessarily the opinion of the JG
team):

I want the free VMs to be as good as the proprietary ones, i really do. And because i want that a
lot, i wanna help to make that happen, i don't want to just sit and wait. But how can i help?

Well, if i would contribute with code to the free VMs that would be perfect, that would be a great
contribution. But i don't think i'm that good hacker and i'm not very interested in digging into
the code of the VMs - so i take another path: i help to test and give the GCJ/Kaffe team some
feedback by actually _using_ their VMs. (Is there anything more fulfilling in free software
development than to see people actually using the software you made and giving feedback?)

Plus, by testing our code in the free VMs we garantee JG will always run in the free VMs, which is
important if you want JG to get into the distros and succeed as a viable free development
platform.

Cheers,
J.V.

Ok, i re-emerge java-gnome-2.8.3 with the new ebuilds.
 
Changed me Makefile to:
-------------------------

LIBS=-lgtkjava-2.4 -lgladejava-2.8 -lgnomejava-2.8

-------------------------

This works fine on my gentoo with my

gcc-Version 3.4.3 20050110 (Gentoo Linux 3.4.3.20050110,
ssp-3.4.3.20050110-0, pie-8.7.7)

Solution 0:

Make sure you're running java-gnome-2.8.3 . It depends on the current
stable releases of the lib*java series. (See my earlier email).

Solution 1:

Use a real [ie, Sun or IBM] Java VM, not GCJ. 

Solution 2:

The actual Java bytecode interpreter from GCJ is "gij", not "gcj".
"gcj" (without -C) means compile to native code.

`which gij` on my system reports
"/usr/i686-pc-linux-gnu/gcc-bin/3.4.3/gij" .
HINT 1: make sure gcc-config is set right.
HINT 2: Be using >=GCC 3.4.3

[Personal opinion: the bias in the examples towards GCJ is premature, in
my opinion. Once GCJ 4 stabilizes, we'll be closer. java-gnome DOES run
under gcj 3.4, however, and the applications I write build under it,
which is awesome. I just don't much care for the error reporting you get
from GCJ. Real Java VMs are cleaner with their compiler errors and
exceptions stacks]

Solution 3:

I think I've seen something like your "Duplicate class" problem. It
happened when when java-gnome was compiled with one version of
GCJ/libgcj, but run against a different version of libgcj If you have
upgraded your GCC (where GCJ comes from) since you last built
java-gnome, re-emerge.

NOTE: libgtkjava-2.6 AND java-gnome-2.10 ARE NOT YET AVAILABLE ON
GENTOO. THEY DEPEND ON GNOME 2.10, WHICH IS GOING INTO THE TREE TODAY.
THEN, AND ONLY THEN, CAN WE RELEASE EBUILDS FOR java-gnome. EVEN THEN,
THEY WILL BE HARD MASKED UNTIL GNOME 2.10 MOVES INTO ~arch.

Give us a couple days, friends. We'll get you there.

That's because I haven't released a set of ebuilds for gtk2.6 or
lib*java 2.10 yet, so the fact you're mixing gtk 2.6 with java-gnome 2.8
stuff is at least part of your problem.

[Someone contributed a bug with a libgtk-java 2.6 ebuild. I eyeballed
it, but I haven't tested yet. Is that what you're using? The fact you're
having problems with it isn't a great sign, but I suspect your real
issue is API mixing, as mentioned]

The known-good Gentoo ebuilds are listed here:
http://www.operationaldynamics.com/reference/software/gentoo/#java-gnome
Give it a few days, and I'll have new ebuilds for java-gnome 2.10 in
there.

you are missing the l (link) - should be -lgtkjava-2.6.

Should be gtkjava-2.6, etc.  Sorry for the incorrect posting earlier.

Re: [Java-gnome-developer] Java gtk does not work anymore after gentoo update

[Abcdefg <ab...@so...>]

Thanks for your help, but it doesn't work yet, I changed my Makefile to
this:

JAVAC=gcj -C
JAVA=gij
GCJ=gcj

INCLUDES=/usr/share/libgtk-java-2.6/lib/gtk2.6.jar:/usr/share/libglade-java-2.8/lib/glade2.8.jar
LIBS=-lgtkjava2.6 -lgladejava2.8
LIBPATH=/usr/lib
FILES=Example.java
MAIN=Example
TARGET=Example

all:
${JAVAC} -classpath ${INCLUDES} ${FILES}

run:
${JAVA} -Djava.library.path=${LIBPATH} -classpath .:${INCLUDES} ${MAIN}

native:
${GCJ} -classpath ${INCLUDES} ${LIBS} --main=${MAIN} -o ${TARGET} ${FILES}

clean:
rm -f *.class

But I still have the same errors as described in the last mail

Also note that the error happens both with gcj and the Makefile and the
'normal' java (blackdown) because when I type
javac Example.java
and than
java -classpath
".:/usr/share/libgtk-java-2.6/lib/gtk2.6.jar:/usr/share/libglade-java-2.8/lib/glade2.8.jar
This is the error:
Exception in thread "main" java.lang.NoSuchMethodError:
org.gnu.gtk.Widget.makeWidget(I)Lorg/gnu/gtk/Widget;
at org.gnu.glade.LibGlade.getWidget(LibGlade.java:202)

at org.gnu.glade.LibGlade.<init>(LibGlade.java:60)
at Example.<init>(Example.java:19)
at Example.main(Example.java:11)

could the problem be that I have libglade-java version 2.8 and gtk+-2.6? I
haven't found an ebuild for the 2.10 version

Thanks,
David

Two simple issues here:

1) You are using the gtk 2.4 jarfile but trying to link with the gtk2.6 shared 
object.  Change to use the 2.6 jar file please.

2) A while ago (december timeframe i think) we changed the name of our
shared objects.  Instead of -lgtkjar2.6 you should use -lgtkjava2.6.

I should be able to send you a makefile later today - when i get home.

Your INCLUDES is still pointing to the gtk2.4.jar even though you now
have a gtk2.6.jar. I don't use gentoo so I don't know exactly where the
file is located, but basically you should replace
"/usr/share/libgtk-java-2.4/lib/gtk2.4.jar" in INCLUDES by the full path
of "gtk2.6.jar".

If that doesn't solve it, don't hesitate to post back.

[Java-gnome-developer] Java gtk does not work anymore after gentoo update

[Abcdefg <ab...@so...>]

Hi,

I updated my gentoo install (emerge -uD world) but now java gtk does not
work anymore :( I think it has someting to do with gtk that updated form 2.4
to 2.6

I have tried a lot of different versions, this is what I currently have but
I also tried older version of libgtk-java(2.4) with the older version of
gtk(2.4):
dev-java/libglade-java-2.8.2.2
x11-libs/gtk+-2.6.2
dev-java/libgtk-java-2.6.0

This is the Makefile I use:

INCLUDES=/usr/share/libgnome-java-2.8/lib/gnome2.8.jar:/usr/share/libgtk-java-2.4/lib/gtk2.4.jar:/usr/share/libglade-java-2.8/lib/glade2.8.jar
LIBS=-lgtkjar2.6 -lgladejar2.8
LIBPATH=/usr/lib
FILES=Example.java
MAIN=Example
TARGET=Example

# The actual makefile rules

all:
${JAVAC} -classpath ${INCLUDES} ${FILES}

run:
${JAVA} -Djava.library.path=${LIBPATH} -classpath .:${INCLUDES} ${MAIN}

native:
${GCJ} -classpath ${INCLUDES} ${LIBS} --main=${MAIN} -o ${TARGET} ${FILES}

clean:
rm -f *.class

This is the error when I type 'make native':

gcj -classpath
/usr/share/libgnome-java-2.8/lib/gnome2.8.jar:/usr/share/libgtk-java-2.4/lib/gtk2.4.jar:/usr/share/libglade-java-2.8/lib/glade2.8.jar
-lgtkjar2.6 -lgladejar2.8 --main=Example -o Example Example.java
/usr/lib/gcc-lib/i386-pc-linux-gnu/3.3.5/../../../../i386-pc-linux-gnu/bin/ld:
cannot find -lgtkjar2.6
collect2: ld returned 1 exit status
make: *** [native] Error 1

This is the error I get when I type javac Example.java and than java
Example:

Exception in thread "main" java.lang.NoSuchMethodError:
org.gnu.gtk.Widget.makeWidget(I)Lorg/gnu/gtk/Widget;
at org.gnu.glade.LibGlade.getWidget(LibGlade.java:202)

at org.gnu.glade.LibGlade.<init>(LibGlade.java:60)
at Example.<init>(Example.java:19)
at Example.main(Example.java:11)

when I type make && make run it does compile and run but the program does
not work (nothing happens when I click a button)

This is the program I
use:http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/GladeWidgetPropertiesAndEvents

I dont know what those errors mean or what to do :(

Do you know what the problem can be? Also could a gentoo user please send
his Makefile and the versions you use?

I wished that when I type import org.gnu.gtk.* it just worked.. ;) Always
when I program something in java I spend a lot of time finding the classpath
and other stuff I don't understand..

I'm currently pretty desperated because I;m working on a program and can't
code now :(

Any help very appreciated,
David

[Java-gnome-developer] binary builds of stable releases for win32

[Simon G. <si...@sg...>]

Is it possible to have binary builds for win32 available from the main site.

We are only interested in the stable versions.  It seems at least one of you guys
have managed to build it, and it would be really great for us to be able to use
GTK on windows from our Java App, because Swing is just too horrible!

I think targeting java developers that have to deploy to Win32 is a good aim,
it will promote adoption.
And providing binary builds for stable releases would really help.
