<p><strong>Note:</strong> This configuration is needed if you are
going to monitor Tomcat remotely. If you are going
to monitor it locally, using the same user that Tomcat runs with, then
with Java 6 it is not needed at all, and with Java 5 it is as simple as
adding <code>-Dcom.sun.management.jmxremote</code>, see Java documentation.</p>
<p>The Oracle website includes the list of options and how to configure JMX Remote on Java 5:
<a href="http://docs.oracle.com/javase/1.5.0/docs/guide/management/agent.html">
http://docs.oracle.com/javase/1.5.0/docs/guide/management/agent.html</a>
and on Java 6:
<a href="http://docs.oracle.com/javase/6/docs/technotes/guides/management/agent.html">
http://docs.oracle.com/javase/6/docs/technotes/guides/management/agent.html</a>.
</p>
<p>The following is a quick configuration guide for Java 5:</p>
<p>Add the following parameters to <code>setenv.bat</code> script of your
Tomcat (see <a href="RUNNING.txt">RUNNING.txt</a> for details).<br>
<em>Note:</em> This syntax is for Microsoft Windows. The command has
to be on the same line. It is wrapped to be more readable. If Tomcat is
running as a Windows service, use its configuration dialog to set
java options for the service.
For un*xes remove <code>"set "</code> from beginning of the line.

Now you can find the manager at <em>${manager.servletExamples.0.name}</em> property
and can access all properties from this manager with <em>${manager.servletExamples.0.[manager attribute names]</em>}.
The result object counter from MBeans is stored ad ${manager.length} property.
