#-----------------------------------------------------------------
# ex4.py - Jython implementation of example script 4
#-----------------------------------------------------------------
#
# The purpose of this example is to demonstrate the invocation
# of some useful problem-determination actions involving traces
# and thread dumps.
#
# This script it can be included in the wsadmin command invocation like this:
#
# wsadmin -lang jython -f ex4.py server1 mynode
#
# or the script can be execfiled from the wsadmin command line like this:
# wsadmin> execfile ("ex4.py") or execfile("ex4.py")
# wsadmin> ex4("server1", "mynode")
#
# The script expects one parameter:
# arg1 - server name
# arg2 - node name
#
# This example demonstrates many wsadmin features:
#
# - The use of the AdminControl object to locate running MBeans
# - The use of the AdminControl object to getAttributes from running MBeans
# - The use of the AdminControl object to invoke operations on running MBeans
# - The use of the Help object to display MBean information
