HP Integrity NonStop H-Series - Manual (Page 224)

The basic architecture of JSF is based on the Model-View-Controller (MVC) design pattern. The
key components of this design pattern are:
• Model
This block contains the business logic of the application and handles the corresponding data.
• View
This is the presentation layer that contains the user-interface code and comprises JSF pages.
• Controller
This block handles all user interactions with the application and constitutes Faces servlets.
Components in a MyFaces Application on NonStop
The components used by MyFaces applications to run on NonStop systems are as follows:
• Web Clients
• TCP/IP Subsystem
• TS/MP PATHMON Process
• iTP WebServer
• NonStop Servlets for JavaServer Pages
Web Clients
Web clients, such as browsers, are programs that provide a graphical user interface and can
communicate directly with the iTP WebServer.
TCP/IP Subsystem
The TCP/IP subsystem uses the TCP/IP protocol to allow processes on a NonStop system to
communicate with each other.
The following types of TCP/IP versions are available on HP Integrity NonStop systems:
• Conventional TCP/IP
• TCP/IPv6
For more information on conventional TCP/IP, see the TCP/IP Configuration and Management
Manual.
For more information on TCP/IPv6, see the TCP/IPv6 Configuration and Management Manual.
TS/MP PATHMON Process
The PATHMON process provides centralized monitoring and control of a TS/MP environment
comprising server classes and objects types.
For more information on conventional TCP/IP, see the HP NonStop Pathway/iTS System Management
Manual.
iTP WebServer
An iTP WebServer is a NonStop web server, which provides a range of services for running an
online commercial or informational enterprise on the Web.
The core process of the iTP WebServer is httpd, which acts as a File server and a
Message-switching facility.
For more information on iTP WebServer, see the iTP Secure WebServer System Administrator's
Guide.
