Chapter 7 Deploying Web Applications in Apache Tomcat

Overview

This section discusses PowerDesigner support for specific constructs:

• Servlet - a Java component for Web Applications.
  
  Servlets can be used to render dynamic web contents, generate web pages based on the results returned by an EJB, or implement Web Services.
  
  PowerDesigner supports servlet creation, generation and deployment.
• Java Server Page (JSP) - an HTML page with Java source code and JSP specific tags.
  
  It is easier to edit and modify than a servlet.
  
  When a JSP is deployed into a server, it is transformed into a servlet.
  
  PowerDesigner supports JSP creation, generation and deployment.
• Web Services - can be implemented in different ways. For Apache Tomcat, PowerDesigner supports the JAXM model and the JAX-RPC model. The JAXM model uses a special servlet model to implement a Web Service. The JAX-RPC model converts a normal Java class into a servlet.
• Apache Tomcat - a Java based open source JSP/Servlet container.
  
  The latest version of Tomcat supports Web Services: JAXM, JAX-RPC and AXIS.
  
  Apache Tomcat is widely used because it supports JSP/Servlet, and Web Services, it is free, fast and easy to manage.
