Wildfly10 client connection to JMX subsystem

[rbenkovitz]

Hello:

I am attempting to get a connection to the JMX sysbsytem.  The most recent document I've found on how to achieve this is located here:

https://docs.jboss.org/author/display/WFLY8/JMX+subsystem+configuration

However, this approach doesn't seem to work.  First, I am getting warnings about http-remoting-jmx service being deprecated, and to use remote+http.  However, attempting to use that service (not sure if I formatted it correctly) yields a "service not found" error.  Using the older one, I keep getting this error:

Exception in thread "main" java.io.IOException: Operation failed with status WAITING

Is there an updated document on how to get this connection for WildFly 10?  Also, what port should I be attempting to connect to?  I've tried 8080, 9990, and 9999, all to no avail.

BTW, I'm basically using "full-ha" profile in the domain.xml configuration file provided with WildFly 10.

Thanks for any help you can give.

I think there is nothing special to WildFly regarding JMX. If you check the Oracle documentation Creating a Custom JMX Client (The Java™ Tutorials > Java Management Extensions (JMX) > Remote Managem…

you will also find a few simple examples.

You should take the WildFly management port. So the URL should look like

service:jmx:remote+http://localhost:9990

But you should also make sure that the WildFly jars (from $JBOSS_HOME/modules/system/layers/base/) are included in the Java classpath.

Thank you for the reply Wolfgang - much appreciated.

I've tried to connect using the URL you mentioned above, but I keep getting an "Unknown service name" exception as below:

serviceURL = service:jmx:remote+http://172.31.62.219:9990

Exception in thread "main" java.io.IOException: Unknown service name

You mention the "WildFly jars" - which ones?  I'm currently including the $JBOSS_HOME/bin/client/jboss-client.jar file, but nothing else specific to jmx - should I be including other jars?

Thanks again.
