New Features in the HP NSJSP Implementation
New Features in the HP NSJSP Implementation
New features incorporated in the HP NSJSP implementation are described below:
J2EE Standards Support
NSJSP 5.0 implements the Java Servlet 2.4 and JavaServer Pages 2.0 specifications
by porting Tomcat version 5.0.28. For more information about Tomcat version 5.0, see
the Apache Jakarta Tomcat 5 Servlet/JSP Container documentation at
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/index.html.
Standalone Application Deployer
NSJSP 5.0 supports a standalone application deployer. In prior versions of NSJSP,
various forms of application deployment (such as, static deployment and dynamic
deployment) have existed. In NSJSP 5.0, a client deployer is supported which
validates, compiles, and deploys a web application to a live NSJSP container.
Customer web applications can now be validated and compiled before they are placed
in a production environment.
For more information about using the standalone application deployer, see Deploy
Using the Standalone Application Deployer on page 3-16.
For more information about the client deployer, see the documentation at
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/deployer-howto.html.
Complete Server Monitoring
NSJSP 5.0 supports complete server monitoring. You can monitor NSJSP servers in
real-time. Using JMX technology and the manager web application, a complete server
status reports the status of each web application as well as its associated statistics
counters in the entire container. Using the manager web application, you can query for
the following status information:
•
The current status of the NSJSP container
•
The status of an individual NSJSP ServerClass process
•
Summary of statistics information of the NSJSP container
•
Summary of statistics information of an individual NSJSP ServerClass process
•
The detailed statistics information of an individual NSJSP ServerClass process
For more information about server monitoring, see Section 5, Manager Web
Application.
Enhanced JSP Runtime Engine
NSJSP 5.0 uses the Jasper 2 JSP Engine to implement the JavaServer Pages 2.0
specification. Jasper 2 has been redesigned to improve performance over the original
