#-----------------------------------------------------------------
# ex2.py - Jython implementation of example script 2
#-----------------------------------------------------------------
#
# The purpose of this example is to show a potentially useful
# sequence of common actions using the scripting client wsadmin.
# This example is the reverse of example ex1, albeit somewhat simpler.
# It stops a server on a given node, uninstalls the given application,
# and removes the server from the configuration.
#
# We assume an environment
# in which the scripting client is attached to the Network Deployment
# manager, but much of this script could be used in a base install.
#
# This script it can be included in the wsadmin command invocation like this:
# wsadmin -lang jython -f ex2.py serverX nodeY myapp
#
# or the script can be execfiled from the wsadmin command line like this:
# wsadmin> execfile ("ex2.py") or execfile("ex2.py")
# wsadmin> ex2("serverX", "nodeY", "myapp")
#
# The script expects some parameters:
# arg1 - server name
# arg2 - node name
# arg3 - application name
#
# This example demonstrates many wsadmin features:
#
# - The use of the AdminApp object to uninstall an application
# - The use of the AdminControl object to locate running MBeans
# - The use of the AdminControl object's "stopServer" command
# - The use of the AdminConfig object to remove objects from the configuration
# - The use of the AdminConfig object to find objects in the configuration
# - The use of the AdminConfig object to save the configuration
