Running an SWT program without Eclipse

[coverslide]

Hi folks, I can't seem to figure out a simple Hello World swt program. I can't do it through eclipse because I access my dev machine through a shell. I compiled it successfully with javac (i am using openjdk) like this:



javac HelloSWT.java -cp swt.jar


swt.jar I copied from /usr/lib/java/swt-gtk-3.5.jar to the same directory after installing the libswt-gtk-3.5-java package. I put HelloSWT.class and swt.jar in the same directory on my test machine, and also installed the packages libswt-gtk-3.5-java and libswt-gtk-3.5-jni.
Trying to run it I get this:



richard@rhmint ~/p/java/HelloSWT $ java HelloSWT
Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/swt/widgets/Display
at HelloSWT.main(HelloSWT.java:8)
Caused by: java.lang.ClassNotFoundException: org.eclipse.swt.widgets.Display

... 1 more


I've added "-cp swt.jar", and "-Djava.library.path=." and different combinations of both. I'm not sure what else I need to do to get it work.

I don't think it's relevant, but the source code to the hello world program is here:



import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class HelloSWT
{
public static void main(String[] args)
{
Display display = new Display();
Shell shell = new Shell(display);
shell.setText("Hello World!");
shell.open();
while(!shell.isDisposed())
{
if(!shell.isDisposed())
{
display.sleep();
}
}
display.dispose();
}
}

Arf, misread the OP... You could always just unpack the jar.
