I am a real newbie in this subject of JMX. I am using MyEclipse/Eclipse JBoss 3.2.5 and I would like to use JMX. Do I need to download something to be able to import "javax.management.XXX"? If so, from where?
The .jar files you need to use JMX are shipped with JBoss, jboss-jmx.jar in the lib directory. This is more of an Eclipse question than JMX one, however. There is a project called JBoss-IDE you may want to use.
