Quick start mbean

Client Mbean

Using a JMX client one can connect to a container Server MBeans and get information very easily. On this blog I have wrote about Jconsole and JvisualVM.

My colleague, Alexander Barbosa, wrote this nice Tutorial to get info on Heap using Mbean. Basically the information comes from the `java.lang:type=Memory`. To get heap or non-heap memory.

	ObjectName memoryMXBean = new ObjectName("java.lang:type=Memory");

You may need to add the credentials for connection and using a map this can be done quick straightforward:

		credentials[0] = "admin";
		credentials[1] = "admin";
		map.put(JMXConnector.CREDENTIALS, credentials);

		// passing server credentials
        JMXConnector jmxConnector = JMXConnectorFactory.connect(serviceURL, map);

Silly mistakes to avoid:

Congratulations you forgot the `.java` part – there is nothing my sully than that:

$ javac -classpath .:$$JBOSS_HOME/bin/client/jboss-client.jar jmxTesterror: 
Class names, 'jmxTest', are only accepted if annotation processing is explicitly requested
