public class swtmenuexample {     static oleclientsite clientsite;     static oleframe frame;     static file file;     static shell shell;     static keylistener keylistener;      public static void main(final string[] args) {         final display display = new display();         shell = new shell(display);          shell.setsize(800, 600);         shell.settext("word example");         shell.setlayout(new filllayout());          try {             frame = new oleframe(shell, swt.none);             // esto abre un documento existente             // clientsite = new oleclientsite(frame, swt.none, new             // file("doc1.doc"));             // esto abre un documento en blanco             // clientsite = new oleclientsite(frame, swt.none, "word.document");             addfilemenu(frame);             system.out.println(" in run method ");         } catch (final swterror e) {             system.out.println("unable open activex control");             display.dispose();             return;         }         keylistener = new keylistener() {              public void keyreleased(keyevent paramkeyevent) {              }              public void keypressed(keyevent paramkeyevent) {                 // todo auto-generated method stub                 if (((paramkeyevent.statemask & swt.ctrl) == swt.ctrl)                         && (paramkeyevent.keycode == 's')) {                     joptionpane.showmessagedialog(null,                             "ctrl+s pressed down initial ",                             "warning message", joptionpane.warning_message);
