NonStop Servlets for JavaServer Pages
The NonStop Servlets for JavaServer Pages (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 JavaServer Pages (NSJSP) 6.0 System
Administrator's Guide.
Message Flow in an Axis2/Java Application on NonStop
Figure 6-2 shows the message flow of an application, based on an Axis2/Java web application.
Figure 6-2 Message Flow of Axis2/Java Application
An Axis2/Java message flows through all the components in the following sequence:
1. Web client sends Axis2/Java-specific request to the TCP/IP sub-system through a web
browser.
2. The TCP/IP sub-system sends the request to the httpd process of the iTP WebServer. If
you are using conventional TCP/IP, the request is sent to the distributor process of iTP
WebServer. But if you are using Parallel TCP/IP Library or TCP/IPv6, the request is sent to
the listener
httpd process.
3. The httpd processes of the iTP WebServer communicate with the NSJSP processes either
using Pathsend calls through TS/MP or directly with an NSJSP process using file system
