我正在尝试在Java应用程序（在NetBeans上）中获取当前显示，但它一直在抛出一个例外，我在网上没有任何有用的东西。
这是我的代码：
@Override
public Object execute(ExecutionEvent event) throws ExecutionException {
try {
System.out.println("Step 1 in Execute in EmailHandler.");
Display display = Display.getCurrent();
// Display display = PlatformUI.getWorkbench().getDisplay();
System.out.println("Step 2 in Execute in EmailHandler.");
Shell shell = new Shell(display);
OleFrame frame = new OleFrame(shell, SWT.NONE);
// This should start outlook if it is not running yet
OleClientSite site = new OleClientSite(frame, SWT.NONE, "OVCtl.OVCtl");
System.out.println("Step in Execute in EmailHandler.");
site.doVerb(OLE.OLEIVERB_INPLACEACTIVATE);
// now get the outlook application
OleClientSite site2 = new OleClientSite(frame, SWT.NONE, "Outlook.Application");
OleAutomation outlook = new OleAutomation(site2);
OleAutomation mail = invoke(outlook, "CreateItem", 0 /* Mail item */).getAutomation();
setProperty(mail, "To", "g.dw@hotmail.be"); // Empty but could also be predefined
setProperty(mail, "Bcc", "test@gmail.com");
setProperty(mail, "BodyFormat", 2 /* HTML */);
setProperty(mail, "Subject", "Test mail");
setProperty(mail, "HtmlBody","<html>Hello<p>, please find some infos here.</html>");
File file = new File("c:/temp/test.txt");
if (file.exists()) {
OleAutomation attachments = getProperty(mail, "Attachments");
invoke(attachments, "Add", "c:/temp/test.txt");
} else {
MessageDialog.openInformation(shell, "Info","Attachment File c:/temp/test.txt not found; will send email with attachment");
}
invoke(mail, "Display"/*"Send"*/); // Or "Display" in place of "Send"
}
catch (Exception e) {
JOptionPane.showMessageDialog(null, e);
}
return null;
}
例外发生在线路Display display = Display.getCurrent();正如您在下一行中看到的那样，我尝试以另一种方式获取当前显示。
这是我使用Display.getCurrent()方法遇到的错误：

有人知道解决方案吗？
非常感谢！
我发现了我的问题！我添加了SWT.Jar作为罐子，而不是整个库。现在，我将其添加为库，不再抛出例外！： - ）
