16 <p><strong>Note:</strong> This configuration is needed if you are
17 going to monitor Tomcat remotely. If you are going
18 to monitor it locally, using the same user that Tomcat runs with, then
19 with Java 6 it is not needed at all, and with Java 5 it is as simple as
20 adding <code>-Dcom.sun.management.jmxremote</code>, see Java documentation.</p>
21
22 <p>The Oracle website includes the list of options and how to configure JMX Remote on Java 5:
23 <a href="http://docs.oracle.com/javase/1.5.0/docs/guide/management/agent.html">
24 http://docs.oracle.com/javase/1.5.0/docs/guide/management/agent.html</a>
25 and on Java 6:
26 <a href="http://docs.oracle.com/javase/6/docs/technotes/guides/management/agent.html">
27 http://docs.oracle.com/javase/6/docs/technotes/guides/management/agent.html</a>.
28 </p>
29 <p>The following is a quick configuration guide for Java 5:</p>
30 <p>Add the following parameters to <code>setenv.bat</code> script of your
31 Tomcat (see <a href="RUNNING.txt">RUNNING.txt</a> for details).<br>
32 <em>Note:</em> This syntax is for Microsoft Windows. The command has
33 to be on the same line. It is wrapped to be more readable. If Tomcat is
34 running as a Windows service, use its configuration dialog to set
35 java options for the service.
36 For un*xes remove <code>"set "</code> from beginning of the line.

68 <p><strong>Note:</strong> The JSR 160 JMX-Adaptor opens a second data channel
69 on a random port. That is a problem when you have a local firewall installed.
70 To fix it, configure a <code>JmxRemoteLifecycleListener</code>, as described
