Inside StartupListener.java add:
Note: Using JDK 1.5 with the JAVA_OPTS and JConsole is optional, most app servers 
already have a MBean server, and MC4J (http://mc4j.sourceforge.net/) provides a JMX Console
for most of them.
At line 10 added 53 lines.
Inside the tomcat startup script, ensure these JAVA_OPTS are set:

JAVA_OPTS="
-Dcom.sun.management.jmxremote.port=9002 
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.ssl=false 
-Djava.awt.headless=true"

(Note: Under Windows, I started tomcat5w.exe and set the above properties in the Java
tab, in the textfield entitled 'Java Options').

Then, if you are using Spring, add this to your applicationContext-hibernate.xml file:

{{{

    <bean id="jmxExporter"
        class="org.springframework.jmx.export.MBeanExporter">
        <property name="beans">
            <map>
                <entry key="Hibernate:type=statistics">
                    <ref local="statisticsBean" />
                </entry>
            </map>
        </property>
    </bean> 

    <bean id="statisticsBean" class="org.hibernate.jmx.StatisticsService">
        <property name="statisticsEnabled">
            <value>true</value>
        </property>
        <property name="sessionFactory"><ref local="sessionFactory"/></property>
    </bean>

}}}

and then set the hibernate.generate_statistics property in your 
applicationContext-hibernate.xml file:

{{{
	<prop key="hibernate.generate_statistics">true</prop>
}}}

When you browse the MBeans (using JConsole.exe - which lives in the bin dir of your JDK 1.5 
distribution), you should see Hibernate, if you double click on that node, you should see
the Statistics Bean.

Tomcat 5 already contains the MX4J libraries and your AppFuse project should 
already have the Hibernate libraries in the runtime classpath.  Below are a couple of screenshots.

If you are not using Spring, inside StartupListener.java (inside contextInitialized method) add:

At line 31 changed 1 line.
After starting up AppFuse, you should be able to attach to the server using JConsole.  From there, you should see the Hibernate MBean where you can view the statistics that have been collected.
After starting up AppFuse, you should be able to attach to the server using JConsole (port 9002, as in the config above).  From there, you should see the Hibernate MBean where you can view the statistics that have been collected.
