Tomcat JMX Resources

<Server ...>
...
<Listener className="org.apache.catalina.mbeans.JMXAdaptorLifecycleListener"
          namingPort="8083" port="8084" host="myhost" />
...
</Server>

See this page for details:
http://tomcat.apache.org/tomcat-5.5-doc/monitoring.html

Here is how to build it from the Tomcat 5.5 source tree:

First, set CATALINA_HOME to the root of your unpacked binary distribution of
Tomcat 5.5.x.

Next build the JMXAdaptorLifecycleListener like this:

$ javac -classpath $CATALINA_HOME/server/lib/catalina.jar:$CATALINA_HOME/bin/commons-logging-api-1.1.1.jar container/catalina/src/share/org/apache/catalina/mbeans/JMXAdaptorLifecycleListener.java

Then copy the resulting class file into place like this:

mkdir -p $CATALINA_HOME/server/lib/org/apache/catalina/mbeans
cp container/catalina/src/share/org/apache/catalina/mbeans/JMXAdaptorLifecycleListener.class $CATALINA_HOME/server/lib/org/apache/catalina/mbeans

    ArrayList list = MBeanServerFactory.findMBeanServer(null);
    MBeanServer mbeanServer = (MBeanServer) list.get(0);
    out.print("MBeanServer: " + mbeanServer + "<br>");

    String domain = mbeanServer.getDefaultDomain();
    out.print("Default domain: " + domain + "<br>");

    Set namesSet = mbeanServer.queryNames(null, null);
    Object[] objectNames = namesSet.toArray();
    out.print("mbean object names: <br>");
    for (int x = 0; x < objectNames.length; x++)
    {
        out.print(objectNames[x] + "<br>");
    }

Tomcat Running PHP via CGIServlet
---------------------------------

The CGIServlet needs to be patched.

Also PHP_SELF becomes "/test5.php/test5.php", when it should be "/test5.php".

With this setup you cannot change the open_basedir then and you cannot use
suexec to switch php users.  PHP may only open files that are within
directories listed in open_basedir.
