<p>
<ol>
<li>Call the methods in the MXBean directly within the same
Java virtual machine.
<blockquote><pre>

// Get the standard attribute "VmVendor"

<p>Or by calling the
{@link java.lang.management.ManagementFactory#getPlatformMXBean(Class)

// Get the standard attribute "VmVendor"
String vendor = mxbean.getVmVendor();

</blockquote>
<p>
</li>
<li>Construct an MXBean proxy instance that forwards the
method calls to a given MBeanServer:<p>
<pre>

<li>Go through a <tt>MBeanServerConnection</tt> connecting

</pre>
<p>A proxy is typically used to access an MXBean
