Object Names and Attributes of MBeans
type=Manager, path=/sca6url/examples, and host=localhost represent
the property-value pairs.

Catalina:type=NamingResources,resourcetype=Context,path=/sca6ur
l,host=localhost
where,
Catalina represents the domain.
type=NamingResources, resourcetype=Context, path=/sca6url, and
host=localhost represent the property-value pairs.

JMImplementation:type=MBeanServerDelegate
where,
JMImplementation represents the domain.
type=MBeanServerDelegate represent the property-value pairs.
The object name might include the property-value pairs that have unusual values, such
as, none and URI. In the following example, the J2EEApplication and the
J2EEServer properties have the value none:
NSJSP:type=JspMonitor,name=jsp,WebModule=//localhost/sca6url/exa
mples,J2EEApplication=none,J2EEServer=none
More information is provided on page A-7.
For more information on the object name, see
http://java.sun.com/javase/6/docs/api/javax/management/ObjectName.html.
An MBean provides the state and details of the managed components in the form of
attributes. Each attribute is denoted by a unique attribute name. You can view and
change the state of the component by modifying the value of the attributes. For
example, the attribute, called maxThreads of the MBean instrumenting the Connector
component denotes the number of threads that the Connector can spawn. By
modifying the value of the maxThreads attribute, the number of threads that the
Connector is allowed to spawn can be changed.
You can view all the MBeans in the NSJSP Server Class processes using the NSJSP
Manager application. The MBeans are organized in a tree structure based on the
MBean object names.
The following section explains how the MBeans are organized in a tree structure.
Note.

The NSJSP Manager application enables you to view and modify the values of the MBean
attributes. However, it does not allow you to invoke methods on MBeans. For more
information on the NSJSP Manager application, see Chapter 4, Managing NSJSP
.

You cannot modify those MBeans whose writable parameter is set to false.
