Class ProcessUtils

java.lang.Object

com.sun.enterprise.universal.process.ProcessUtils

public final class ProcessUtils
extends Object

Includes a somewhat kludgy way to get the pid for "me". Another casualty of the JDK catering to the LEAST common denominator. Some obscure OS might not have a pid! The name returned from the JMX method is like so: 12345
