There are no instances of this class.</p> <p>Since JMX 1.2 this class makes it possible to replace the default MBeanServer implementation. This is done using the <A HREF="../../javax/management/MBeanServerBuilder.html" title="class in javax.management"><CODE>MBeanServerBuilder</CODE></A> class. The class of the initial MBeanServerBuilder to be instantiated can be specified through the <b>javax.management.builder.initial</b> system property. The specified class must be a public subclass of <A HREF="../../javax/management/MBeanServerBuilder.html" title="class in javax.management"><CODE>MBeanServerBuilder</CODE></A>, and must have a public empty constructor. <p>By default, if no value for that property is specified, an instance of <A HREF="../../javax/management/MBeanServerBuilder.html" title="class in javax.management"><CODE>javax.management.MBeanServerBuilder</CODE></A> is created. Otherwise, the MBeanServerFactory attempts to load the specified class using <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Thread.html#getContextClassLoader()" title="class or interface in java.lang"><CODE>Thread.currentThread().getContextClassLoader()</CODE></A>, or if that is null, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Class.html#forName(java.lang.String)" title="class or interface in java.lang"><CODE>Class.forName()</CODE></A>. Then it creates an initial instance of that Class using <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Class.html#newInstance()" title="class or interface in java.lang"><CODE>Class.newInstance()</CODE></A>. If any checked exception is raised during this process (e.g. <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/ClassNotFoundException.html" title="class or interface in java.lang"><CODE>ClassNotFoundException</CODE></A>, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/InstantiationException.html" title="class or interface in java.lang"><CODE>InstantiationException</CODE></A>) the MBeanServerFactory will propagate this exception from within a RuntimeException.</p> <p>The <b>javax.management.builder.initial</b> system property is consulted every time a new MBeanServer needs to be created, and the class pointed to by that property is loaded. If that class is different from that of the current MBeanServerBuilder, then a new MBeanServerBuilder is created. Otherwise, the MBeanServerFactory may create a new MBeanServerBuilder or reuse the current one.</p> <p>If the class pointed to by the property cannot be loaded, or does not correspond to a valid subclass of MBeanServerBuilder then an exception is propagated, and no MBeanServer can be created until the <b>javax.management.builder.initial</b> system property is reset to valid value.</p> <p>The MBeanServerBuilder makes it possible to wrap the MBeanServers returned by the default MBeanServerBuilder implementation, for the purpose of e.g. adding an additional security layer.</p><P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../javax/management/MBeanServer.html" title="interface in javax.management">MBeanServer</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/management/MBeanServerFactory.html#createMBeanServer()">createMBeanServer</A></B>()</CODE><BR> Return a new object implementing the MBeanServer interface with a standard default domain name. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../javax/management/MBeanServer.html" title="interface in javax.management">MBeanServer</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/management/MBeanServerFactory.html#createMBeanServer(java.lang.String)">createMBeanServer</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> domain)</CODE><BR> Return a new object implementing the <A HREF="../../javax/management/MBeanServer.html" title="interface in javax.management"><CODE>MBeanServer</CODE></A> interface with the specified default domain name. </TD>⌨️ 快捷键说明
