Ich brauche Hilfe, um ein Bündel in Kura zu erstellen, die eine Swing GUI zeigen. Ich verwende Java und OSGI, um Bundles zu erstellen. Ich betreibe es auf raspberryPI.Java Swing GUI auf Kura
Ich habe diesen Code innerhalb der Aktivator des Bundles:
public void activate(ComponentContext componentContext, Map<String,Object> properties)
{
System.out.println("Sono AstroGUI!!!!");
Runnable runnable = new Runnable() {
public void run() {
createAndShow();
}
};
SwingUtilities.invokeLater(runnable);
}
static void createAndShow() {
JFrame frame = new JFrame("Hello World");
frame.setSize(640,480);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
Aber wenn ich das Bündel laden, kehrt das System diesen Fehler:
Exception in thread "AWT-EventQueue-0" java.awt.HeadlessException: No X11 DISPLAY variable was set, but this program performed an operation which requires it. at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:207) at java.awt.Window.(Window.java:536) at java.awt.Frame.(Frame.java:420) at javax.swing.JFrame.(JFrame.java:225) at com.riccardofontanini.astrogui.AstroGUIActivator.createAndShow(AstroGUIActivator.java:56) at com.riccardofontanini.astrogui.AstroGUIActivator$1.run(AstroGUIActivator.java:47) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:311) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:744) at java.awt.EventQueue.access$400(EventQueue.java:97) at java.awt.EventQueue$3.run(EventQueue.java:697) at java.awt.EventQueue$3.run(EventQueue.java:691) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:75) at java.awt.EventQueue.dispatchEvent(EventQueue.java:714) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:116) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:105) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:101) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:93) at java.awt.EventDispatchThread.run(EventDispatchThread.java:82)
