<ClaimHandler>com.wso2.sample.claim.handler.CustomClaimHandler</ClaimHandler>With this custom claim handler I am trying to demonstrate few use cases,
-
Retrieving claims from an external claim store
-
Modifying/Transforming claims - For example take the first name and last name claims and create a new claim for full name
-
Modifying/Transforming claims using JavaScript - I am using JVM's inbuilt Nashorn JS Engine for this.
