  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());
    		}
    	}
    }
