Where can I get my questions about JMX answered?
By daniel on Jan 20, 2006
JMX is one of the oldest Java Specification Request: it's JSR 3! More recently JMX has been completed with the JSR 160 (JMX Remote API), and both have later been integrated into the J2SE 5.0 platform (Tiger).
Thus, as one of the oldest JSR that's been around, JMX also has one of the oldest mailing-list style forum: the JMX-FORUM. Update: the JMX-FORUM mailing list is now a bit outdated. You will find more information and support on the JMX SDN forum
However, should you wish to try your luck with the JMX_FORUM mailing list here is how it works:
- go to the JMX-FORUM server page
- click on Join or leave the list
- enter your name and email address
- choose your subscription type (regular or digest or ...)
- click on Join JMX-FORUM
That's all! You will receive emails from the list as per your subscription.
After having joined the list, you can simply send your questions to JMX-FORUM@JAVA.SUN.COM
The traffic on the list is quite manageable (a few post per day), and thanks to the registration process, doesn't get spam [crossing my fingers].
Note that you don't need to be registered to browse or search the archive, but you will need to be registered to send mail to the list.
Besides the Java SE documentation on java.sun.com [Tiger's doc index] [Monitoring and Management] [JMX], [JMX Best Practices], and other documentation from the JMX Home Page, you will also find insightful and interesting information in these blogs (and this is in no way an exhaustive list):
- Eamonn's blog: JMX past, present, and future!
- Alan's blog: JConsole, the JVM monitoring agent, attaching to JConsole, and more...
- Mandy's blog: Monitoring and Management of the JVM
- Jean-François's blog: NetBeans and JMX
- Luis-Miguel's blog: Java, JMX, M&M, RMI, security, etc...
- The Aquarium has many informative articles about JMX in GlassFish and J2EE,
- Kedar's blog A thought a day... has also many information about JMX in GlassFish and Sun's AppServer,
- and of course my own blog which you're currently reading.
For JMX newcomers, here is where to look if you're still wondering
what is JMX, and here is where you will find information if you're
looking for JMX Overview, Examples, Tutorial, and more... It does
share quite a mumber of links with this one entry itself though.
You may also want to read Danny Coward blog entry about the new Tiger and Mustang tools that will help you diagnose problems in your application. If you're experiencing troubles connecting with JConsole, then Troubleshooting Connection Problems in JConsole will probably help you to figure out what's going wrong.
Finally, if you're looking for JMX debug information, you may want to read Tracing JMX - What's going on in my MBeanServer?
[OK, I'm cheating, these were forward references in time - but what would you expect from a guy who just read The Hitchhiker's Guide to the Galaxy?]
I hope this information will be helpful to you!
