I'm not sure what you mean. If you use J2SE 5 then you're not using MX4J (unless you put mx4j in the bootclasspath), therefore you will use J2SE JMX monitor with J2SE JMX implementation. If you put MX4J in the classpath, then you will use MX4J JMX monitor with MX4J JMX implementation.

I'm using mx4j 3.01.
Yes, this is possible. NamingService is a portable MBean across JMX implementations, so just put mx4j-tools.jar in the classpath of your J2SE 5 application, and everything will work.

Thanks for your help!
Well JMX is a new target for me and I don't really have much insight in the available mbeans.
I've built a Server application using Spring and a client application using Eclipse RCP. As a communication platform I'm using JMX with just a few simple MBeans and Notification. And yes, I'm using j2se 1.5 on both sides with mx4j on the server side. I didn't know mx4j provides MBeans that can monitor a JVM the way the tiger integrated can. I just thought it might be a good feature to provide a way to look at the server and see how it's doing (and it makes testing for memory leaks etc. easier).
Again, thanks for your help! Torsten.

Cool.

As I told, if you're using J2SE 5, then you're *not* using MX4J JMX implementation. But you can use all MX4J tools (bundled in mx4j-tools.jar) since all tool MBeans are portable.
I didn't know mx4j provides MBeans that can > monitor a > JVM the way the tiger integrated can.
Ah, no. I thought you were referring to javax.management.monitor.* package, which is JMX standard. MX4J does not offer any MBean to monitor the JVM. Those are only available in J2SE 5.

Hi,
no, I use MX4J because it's in the classpath and I use the property -Djavax.management.builder.initial=mx4j.server.MX4JMBeanServerBuilder
And I guess I have decided I'll stick with MX4J.
In addition I'm enabling the j2se JMX Agent through -Dcom.sun.management.jmxremote and be able to watch my server during development cycle. I don't think the customers the product is targeted for will use this feature. Maybe I find a way to manage those MXBeans through MX4J and then monitor them through my Eclipse RCP application.
As a side note, I'm really happy with the huge amount of solutions Java has to offer! Some years ago we built a C++ distributed application which could not use CORBA and thus had to manage everything through low level socket connections. Brrr...
bye, Torsten.
