	For the single server edition of WAS6, you have to set the following
	enviroment virable:
	OCF_RESKEY_profile
	(WAS profile name)


	$0 manages a Websphere Application Server 6(WAS6) as an HA resource

	The 'start' operation starts WAS6.
	The 'stop' operation stops WAS6.
	The 'status' operation reports whether WAS6 is running
	The 'monitor' operation reports whether the WAS6 seems to be working
	(httpd also needs to be working for this case)
	The 'validate-all' operation reports whether the OCF instance parameter (OCF_RESKEY_profileName ) is valid
	The 'methods' operation reports on the methods $0 supports

	This is known to work with the Single Server edition of Websphere.

	The default profile name for the single server edition is:
	$DEFAULT

	The start and stop operations must be run as root.

	The status operation will report a pid of "-" for the
	WAS root process using unless it is run as root.

	If you don't have xmllint on your system, parsing of WAS
	configuration files is very primitive.

	We run servlet/snoop on the seventh transport port listed in
	the config file for the "monitor" operation.
