now throw err mssage :

The parser can't find any root method(s) (entry points for parsing). The parser starts parsing from known method(s) for each GUI toolkit. For example, for Swing it starts from the constructor of a JPanel or JFrame. If the currently parsed class is not a subclass of a Swing component, the parser will try to find a main(java.lang.String[]) method. If it also does not exist, this exception will be shown. Usually this means that you are trying to parse something not supported by WindowBuilder (for example, a non-GUI compilation unit).

Note that even if WindowBuilder can't recognize your code pattern automatically, sometimes you can still teach WindowBuilder to work with it by providing a @wbp.parser.entryPoint JavaDoc hint. For example:

	public class MyClass {
		/**
		 * @wbp.parser.entryPoint
		 */
		public void someNonStandardEntryPoint() {
			JFrame frame = new JFrame();
			...;
		}
	}
