SOLUTION

• The Java Servlet specification defines an application programming interface for communication between the Web server and the application program.
• Servlets are commonly used to generate dynamic responses to HTTP requests.
• They can access inputs provided through HTML forms, apply “business logic” to decide what response to provide, and then generate HTML output to be sent back to the browser.
• In a two-layer Web architecture, an application runs as part of the Web server itself.
• One way of implementing such an architecture is to load Java programs into the Web server.
