JMX Based Administration Feature
JMX Based Administration Feature
NSJSP supports JMX based administration. NSJSP incorporates JMX technology to
manage internal objects (for example, Servers, Services, Hosts, Contexts, Loggers,
and other resource entities).
In prior releases, NSJSP required you to bring down the entire container and change
the configuration file iTP_server.xml to modify container objects. With the support
of JMX MBeans for manageability, objects can now be modified while the container is
running. This arrangement enhances the NSJSP container's availability.
For more information about administering container objects online, see JMX Based
Administration on page 4-9.
For more information about JMX MBeans, see the Apache Jakarta Tomcat 5
Servlet/JSP Container documentation at http://jakarta.apache.org/tomcat/tomcat-5.0-
doc/index.html.
admin Web Application
The admin web application provides a GUI-based interface to administer container
objects and resource modifications using JMX MBeans. The admin web application
uses the Apache Struts framework to implement the administration GUI-based
interface. The Struts framework promotes applications to be based on the Model-View-
Controller (MVC) design. The admin web application uses JSP pages for the View
component. These JSP pages create HTML forms for the operator to specify object
attributes and to initiate various object operations.
Figure 1-6 is an example of the admin user interface.
