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.
NonStop Servlets for JavaServer Pages
The NSJSP 6.0 implementation is a multi-thread, out-of-process servlet container, and a Java web
container that runs on a Java Virtual Machine (JVM) outside the iTP WebServer
httpd process.
NSJSP includes the following components:
• NSJSP Connector
• NSJSP Container
For more information on NSJSP, see the NonStop Servlets for JavaServerPages (NSJSP) 6.0 System
Administrator's Guide.
JDBC Drivers for NonStop SQL/MX
JDBC is an API for the Java programming language that defines how a client may access a
database. It provides methods for querying and updating data in a database. JDBC is oriented
towards relational databases.
The following types of JDBC drivers are available on NonStop systems:
• JDBC Type 2 Driver for NonStop SQL/MX
• JDBC Type 4 Driver for NonStop SQL/MX
For more information on the JDBC Type 2 driver, see the JDBC Driver for SQL/MX Programmer's
Reference Manual.
For more information on the NonStop JDBC Type 4 driver, see the HP NonStop JDBC Type 4
Driver Programmer's Reference Manual.
NonStop SQL/MX
NonStop SQL/MX is a relational database product with the ability to run queries in parallel. It
offers an advantage of scaling, almost linearly, with the number of processors in a NonStop
system.
For more information on NonStop SQL/MX, see the SQL/MX Installation and Management Guide.
Message Flow in a Spring Application on NonStop
Message flow of a Spring web application is similar to that of any other web application deployed
under NSJSP. This section describes the message flow for Spring web application deployed under
NSJSP.
Figure 2-2 illustrates the message flow of an application, based on a Spring web framework.
