MX4J is an implementation of JMX and JMX Remote. These *are* included in J2SE 1.5 (5.0): http://java.sun.com/j2se/1.5.0/docs/api/javax/management/package-frame.html http://java.sun.com/j2se/1.5.0/docs/api/javax/management/remote/package-frame.html However, they are not part of J2SE 1.4: http://java.sun.com/j2se/1.4.2/docs/api/overview-frame.html You have to download these separately, if you want to use Sun's reference implementation under JDK 1.4: http://java.sun.com/products/JavaManagement/download.html Are we both looking at the same thing?
