Spring, JMX and Tomcat 5.5 + MC4J 1.2b9

[etienno]

Hi,

I am trying to make a simple working JMX example with Tomcat 5.5, MC4J 1.2b9.

I have put a simple Spring applicationContext file with this taken from the Spring JMX tutorial (with the proper contextLoader in web.xml):



>>>>
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

<!-- MBean Server IF NOT RUNNING IN TOMCAT -->

<!-- bean id="mbeanServer"
class="org.springframework.jmx.support.MBeanServer FactoryBean" /-->

<!--
this bean needs to be eagerly pre-instantiated in order for the exporting to occur;
this means that it must not be marked as lazily initialized
-->


<bean id="exporter"
class="org.springframework.jmx.export.MBeanExporte r">

<property name="autodetect" value="true" />
<!-- property name="server" ref="mbeanServer" /-->

<property name="beans">
<map>
<entry key="bean:name=testBean1" value-ref="testBean" />
</map>
</property>
</bean>

<bean id="testBean" class="jmx.JmxTestBean">
<property name="name" value="TEST" />
<property name="age" value="100" />
</bean>

</beans>

and my console server log is :

So it seems that the server started correctly? But where did the JMX Server started? Tomcat 5.5 is supposed to have a JMX server included? But when I start the MC4J console (using the default tutorial) I have this error:

Does anyone could help me here? I am pretty sure I am doing some trivial thing wrong (like the RMI registry is not running, or MC4J is not working well?). I have try to run explicitly the JMX server (comment in the spring context file), but it doesn't work either.

Thanks if you can help me.

OK found my mistake.

I have made it work, i have put the need -D in the Tomcat Eclipse starter (Sysdeo) under the Tomcat JVM parameter (not in the catalinastart.bat as I thaught).

-Dcom.sun.management.jmxremote.port=8999
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false

Now I see everything in the MC4J console.

Tks for following...

Etienne.
