The ScriptedDataConnector data connector allows the creation of multiple IdPAttribute objects via a JSR-223 script. Scripts are somewhat easier to write and maintain than native Java code, though they are slower. They can also be changed dynamically since the resolver is a ReloadableService.

Script Context

The script "context" defines the execution environment for the script and provides the following variables:

...

Expand
titleSpecific XML Attributes

Name

Type

Default

Description

language

string

JavaScript

Defines the JSR-223 language to use. The default is ECMA script using either the Rhino (Java 7) or Nashorn (Java 8+) engines.This situation is in flux due to the removal of Nashorn from future Java versions, and plugins are available for V4.1+ whatever scripting implementation is supplied. Plugins are available for that supply one of these options at the deployer's discretion, as Java no longer includes a Javascript implementation.

customObjectRef

string


The name of a Spring Bean defined elsewhere. This bean will be made available to the script with the name "custom".
