  2. The New Bean wizard opens. In the Name field, type in a name for the bean, for example, PrintConvertToBean. Click Finish to close the wizard.
  3. Enter the following code in the design workspace. 
    package beans;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;
public class PrintConvertToBean {

	/**
	 * print input message
	 * @param message
	 */
	public static void helloExample(Document message) {
		if (message == null) {
			System.out.println("There's no message here!");
			return;
		}
		Element rootElement = message.getDocumentElement();
		if (rootElement == null) {
			System.out.println("There's no root element here!");
			return;
		}
		System.out.println("The root element name is:"
				+ rootElement.getNodeName());
		System.out.println("The book categories are:");
		NodeList types = rootElement.getElementsByTagName("category");
		for(int i = 0;i<types.getLength();i++){
			Element child = (Element) types.item(i);
			System.out.println(child.getFirstChild().getNodeValue());
		}
	}
}
