Hello everyone!
This is "helloworld" program but i couldn't even run this :(!
so here is the code:
***************************************************
package swt;
import org.eclipse.swt.*;
import org.eclipse.swt.widgets.*;
public class SWTHello {
public static void main(String[] args) {
try{
24(line number) Display display = new Display();
25 Shell shell = new Shell(display);
26 Label label = new Label(shell, SWT.NONE);
label.setText("Hello World!");
shell.pack();
label.pack();
shell.open();
while(!shell.isDisposed()){
if(!display.readAndDispatch()){
display.sleep();
}
}
display.dispose();
label.dispose();
} catch(Exception e){
System.out.println("Error!");
e.printStackTrace();
}
}
}
******************************************************
i added swt.jar to the project
and as in the tutorial i run program with vm arguments
-Djava.library.path=$HOME/tools/eclipseGTK2.1/plugins/org.ec lipse.swt.gtk._2.1.2/os/linux/x86/
but then i've got a strange error :
Exception in thread "main" java.lang.NoClassDefFoundError:
org/eclipse/swt/internal/gtk/GdkEvent
at swt.SWTHello.main(SWTHello.java:24)
line 24 is Display display = new Display();
what can be wrong? Any idea?
Thank you for your help!
Regards, J.B.

Hello Silenio!
Thank you for your help!
It solved one problem but still there is a problem!
I run it as following
java swt.SWTHello -cp
../../../../../eclipseGTK2.1/plugins/org.eclipse.swt.gtk_2.1 .2/ws/gtk/swt.jar:./../../../../eclipseGTK2.1/plugins/org.ec lipse.swt.gtk_2.1.2/ws/gtk/swt-pi.jar
-Djava.library.path=./../../../../eclipseGTK2.1/plugins/org. eclipse.swt.gtk_2.1.2/os/linux/x86
but now error is different:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/eclipse/swt/widgets/Composite
Regards, J.B!
