<section name="Background">

    <p>We will be using <em>JMX MBeans</em> as the technology for
    implementing manageability of Tomcat.</p>

    <p>One of the key concepts of JMX (and JSR-77) is that each management
    bean has a unique name in the MBeanServer's registry, and that
    management applications can utilize these names to retrieve the MBean
    of interest to them for a particular management operation.
    This document proposes a naming convention for MBeans that allows easy
    calculation of the name for a particular MBean.  For background
    information on JMX MBean names, see the <em>Java Management Extensions
    Instrumentation and Agent Specification</em>, version 1.0, section 6.
    In particular, we will be discussing the String Representation of
    <code>ObjectName</code> instances.</p>

</section>

<section name="Catalina Object Hierarchy">

<p>Tomcat's servlet container implementation, called Catalina, can be
represented as a hierarchy of objects that contain references to each other.
The object hierarchy can be represented as a tree, or (isomorphically) based
on the nesting of configuration elements in the <code>conf/server.xml</code>
file that is traditionally used to configure Tomcat stand-alone.</p>

<p>The valid component nestings for Catalina are depicted in the following
table, with columns that contain the following values:</p>
<ul>
<li><em>Pattern</em> - Nesting pattern of XML elements (in the
    <code>conf/server.xml</code> file) used to configure this component.</li>
<li><em>Cardinality</em> - Minimum and maximum number of occurrences of
    this element at this nesting position, which also corresponds to the
    minimum and maximum number of Catalina components.</li>
<li><em>Identifier</em> - Name of the JavaBeans property of this component
    that represents the unique identifier (within the nested hierarchy),
    if any.</li>
<li><em>MBean ObjectName</em> - The portion of the MBean object name that
    appears <strong>after</strong> the domain name.  For now, it should be
    assumed that all of these MBeans appear in the default JMX domain.</li>
</ul>

<p>In the <em>MBean ObjectName</em> descriptions, several types of symbolic
expressions are utilized to define variable text that is replaced by
corresponding values:</p>
<ul>
<li><em>${GROUP}</em> - One of the standard MBean names of the specified
    "group" category.  For example, the expression <code>${REALM}</code>
    represents the values like <code>JDBCRealm</code> and <code>JAASRealm</code>
    that identify the various MBeans for possible <code>Realm</code> components.</li>
<li><em>${name}</em> - Replaced by the value of property <code>name</code>
    from the current component.</li>
<li><em>${parent.name}</em> - Replaced by the value of property
    <code>name</code> from a parent of the current component, with the
    parent's type identified by <em>parent</em>.</li>
<li><em>${###}</em> - An arbitrary numeric identifier that preserves
    order but has no other particular meaning.  In general, the server will
    assign numeric values to existing instances with large gaps into which
    new items can be configured if desired.</li>
</ul>
