Hi Braun,
I had get Correct wording.
op.get("address").add("profile", "default"); this seems to be used in mode domain management,when use in standalone mode will generate an error as follow：
===========================
{
"outcome" => "failed",
"failure-description" => "No handler for operation read-children-resources at address [
(\"profile\" => \"default\"),
(\"subsystem\" => \"datasources\")
]",
"rolled-back" => true
}
===========================
Could you please help me with "profile" usage.
Thanks a lot,
duanxz
