[Java-gnome-developer] Problems running programs

[Bruno D. <bdu...@be...>]

Hi,

I must be the dumbest man in the world but I cannot compile/run any
Java-Gnome program, whether it's with Eclipse or not !

I'm running Debian/Sid with Sun's JDK 1.4
Jar's are in /usr/share/java :

bdusauso@Tu-144:~/workspace/First$ ls  /usr/share/java
docbook-xsl-saxon651-1.66.1.jar  gnome2.8-2.8.2.jar
gtk2.4-2.4.6.jar
docbook-xsl-saxon65-1.66.1.jar   gnome2.8.jar              gtk2.4.jar
docbook-xsl-saxon651.jar         gnomevfs2.7-2.7.4.jar
gtkhtml2.4-2.4.3.jar
docbook-xsl-saxon65.jar          gnomevfs2.7.jar
gtkhtml2.4.jar
docbook-xsl-xalan25-1.66.1.jar   gnomevte0.11-0.11.13.jar
docbook-xsl-xalan25.jar          gnomevte0.11.jar

And the .so's are in /usr/lib/jni :

bdusauso@Tu-144:~/workspace/First$ ls /usr/lib/jni
libgnomejar2.8.so              libgnomevtejava0.11.so
libgnomejar2.8.so.2.8.2        libgnomevtejava0.11.so.0.11.13
libgnomejava2.8.so             libgtkhtmljar2.4.so
libgnomejava2.8.so.2.8.2       libgtkhtmljar2.4.so.2.4.3
libgnomevfsjar2.7.so           libgtkhtmljava2.4.so
libgnomevfsjar2.7.so.2.7.4     libgtkhtmljava2.4.so.2.4.3
libgnomevfsjava2.7.so          libgtkjar2.4.so
libgnomevfsjava2.7.so.2.7.4    libgtkjar2.4.so.2.4.6
libgnomevtejar0.11.so          libgtkjava2.4.so
libgnomevtejar0.11.so.0.11.13  libgtkjava2.4.so.2.4.6

The program is the first one from the tutorial, that is :

My CLASSPATH is as follows :

bdusauso@Tu-144:~/workspace/First$ echo $CLASSPATH
/usr/lib/j2se/1.4/jre/lib/rt.jar:/usr/share/java:.

bdusauso@Tu-144:~/workspace/First$ cat First.java

import org.gnu.gnome.App;
import org.gnu.gnome.Program;
import org.gnu.gtk.Gtk;

public class First {

        public static void main(String[] args) {
        // Initialization
        Program.initGnomeUI("First", "0.1", args);

        App app = new App("First", "First App");
        app.show();

        Gtk.main();
        }
}

So, when trying "javac First.java", I run into troubles ;) :

bdusauso@Tu-144:~/workspace/First$ javac First.java
First.java:14: package org.gnu.gnome does not exist
import org.gnu.gnome.App;
                     ^
First.java:15: package org.gnu.gnome does not exist
import org.gnu.gnome.Program;
                     ^
First.java:16: package org.gnu.gtk does not exist
import org.gnu.gtk.Gtk;
                   ^
First.java:22: cannot resolve symbol
symbol  : variable Program
location: class First
        Program.initGnomeUI("First", "0.1", args);
        ^
First.java:24: cannot resolve symbol
symbol  : class App
location: class First
        App app = new App("First", "First App");
        ^
First.java:24: cannot resolve symbol
symbol  : class App
location: class First
        App app = new App("First", "First App");
                      ^
First.java:27: cannot resolve symbol
symbol  : variable Gtk
location: class First
        Gtk.main();
        ^
7 errors

It seems javac don't find the packages, but my parameters (CLASSPATH
especially) are right, no ?


Another problem is when running Eclipse. I've set it up like shown in 

http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/EclipseDevelopment

But, when running, Eclipse tells me :

Exception in thread "main"
java.lang.UnsatisfiedLinkError: /usr/lib/jni/libgnomejava2.8.so.2.8.2:
libgtkjava2.4.so: cannot open shared object file: No such file or
directory
	at java.lang.ClassLoader$NativeLibrary.load(Native Method)
	at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1586)
	at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1511)
	at java.lang.Runtime.loadLibrary0(Runtime.java:788)
	at java.lang.System.loadLibrary(System.java:834)
	at org.gnu.gnome.Program.<clinit>(Program.java:74)
	at First.main(First.java:22)


I'm sure i'm doing all things the wrong way, but I don't know how to do
it right :)
Is there a good soul who can help me ?

Regards.
