What’s New in This Manual
NonStop Servlets for JavaServer Pages (NSJSP) System Administrator’s Guide—525644-002
xii
New and Changed Information
•
Enhanced JSP runtime engine. NSJSP uses the new Jasper 2 JSP engine which
includes significant performance improvements over the original Jasper engine.
For more information, see Enhanced JSP Runtime Engine on page 1-14.
•
Support for an enhanced Security Manager. NSJSP allows you to configure which
NSJSP internal packages are protected against package definition and access.
This prevents non-trusted web applications from accessing sensitive NSJSP
internal packages. For more information, see Configuring the Security Manager on
page 3-21.
•
Support for JAASRealm. NSJSP includes support for the JAASRealm user
database. For more information, see JAASRealm on page 3-40.
•
Support for JMX based administration. NSJSP uses JMX technology to manage
internal objects (for example, Servers, Services, Hosts, Contexts, Loggers, and
other resource entities online). In prior releases, you were required to bring down
the entire container and change the configuration file iTP_server.xml to modify
container objects. Because objects can now be modified online, this change
enhances the NSJSP container's availability. For more information, see JMX
Based Administration on page 4-9.
•
Support for a new admin web application which provides a GUI interface for
administering container object and resource modifications using JMX MBeans. For
more information, see admin Web Application on page 4-10.
•
Support for a new manager web application which provides the management
functions for web applications in the NSJSP container. In prior releases, these
functions were provided using the nsjsp_manager (an interactive shell script).
For more information, see Manager Web Application on page 5-1.
•
Support for enhanced NSJSP connector component NSJSPCoyoteConnector.
The connector is managed using JMX MBeans. For more information, see
Enhanced NSJSPCoyoteConnector on page 1-19.
•
No provision for the support of session clustering. NSJSP does not implement
session clustering. Instead, the current session routing mechanism continues to be
used in NSJSP 5.0. For more information see Session Clustering (not supported)
on page 1-19.
•
Discontinuance of external support for NonStop EJB.
