1 Introduction to NSJSP
This chapter describes NonStop Servlets for JavaServer Pages (NSJSP), its
components, and its architecture.
To understand NSJSP, prior knowledge of the following topics is required:

Java Servlets and JavaServer Pages (JSP)
A Java Servlet is a programming object that runs in a server application. It receives
client requests, processes them, and generates responses. For more information
on the Java Servlet 2.5 specification, see
http://jcp.org/aboutJava/communityprocess/mrel/jsr154/index2.html.
JSP is a server side technology that enables you to develop and maintain dynamic
web pages. It extends the functionality of web-based applications by providing
dynamic content from a web server to a client browser over the Hypertext Transfer
Protocol (HTTP). For more information on the JavaServer Pages 2.1 specification,
see http://jcp.org/aboutJava/communityprocess/final/jsr245/index.html.

iTP Secure WebServer concepts, such as, how the iTP Secure WebServer
components are deployed as TS/MP server classes and how the HTTP daemon
(HTTPD) interacts with other components, such as the Common Gateway Interface
(CGI)-Server using pathsend calls.
For more information on the iTP Secure WebServer concepts, see the iTP Secure
WebServer System Administrator’s Guide.
