SourceCafe generates a complete set of multi-tier web application codes based on the best architecture:

Middle tier components
JavaBeans: This class wraps the database table model and represents the business
   entity.
Data Access Object (DAO): You can choose to generate data access logic in a  
   separate layer (DAO). Otherwise, this logic is implemented inside the JavaBeans.
Enterprise JavaBeans (EJB) components: For EJB projects, SourceCafe generates the  
   Entity Beans along with the Remote and the Home interface. The Primary key class is  
   also generated if the entity bean has composite primary keys.
Transfer Object: This is an optional component for EJB application, which is to
   efficiently transfer data by sending a coarse-grained view of the data.

Web tier components
JavaServer Pages: These are for web based user interface presentation list, view and
   edit. You can choose from multiple formats HTML, WML and/or HDML.
Java Servlet: This is for user interface control logic parse user input and connect to the
   back-end to save and delete.
Deployment Descriptor: The XML file defines Servlets and its mapping.
