I imported all the required jar files into build path, and almost all other eclipse class and events, e.g. SWT, widgets, graphics, selectionevents are working. However, but when I try to create an instance of CoolBar and DateTime, found that import these 2 classes are unavailable, and importing SWT.*, SWT.widgets.* doesn't help.

What else jar file I shall import to make the CoolBar and DateTime working?
