• Create Java classes HelloWorld and MainApp under the demo bundle. 
• Create Beans setup document Beans.xml under the src envelope. 
• Create log4J setup document log4j.properties under the src envelope. 
• The last advance is to make all the Java records and Bean Configuration documents and run the application.
