OIM11G + Java: entity adapters vs event handlers

Today I will talk about entity adapter detailed and provide you a link that have a great explanation about event handler too.

Some definitions:

Adapter:Primarily used to automatically complete provisioning tasks.

Event handler:A resource object’s provisioning process contains tasks that must be completed automatically. Once this happened, you have to assign an event handler or an adapter to the RO. Basically an event handler is a software routine and it will process a specific information

Details:

–> It looks like the entity adapter is going to be deprecated. What will replace entity adapter? Probably Entity adapter will be replaced by Event handler. So, why I am writing an article related of entity adapter?Because there are specific cases that event handler can not apply yet. And for this specific case(Child table) pre-insert into OIM 11G.You have to use it to pre-insert entity adapter for a childform.

Starting: Basically my code example will check if the value of one variable column is unique or not. If yes, it will create a record into child form table. If not, it will raise an exception as I will show below:

First item: Java Code.
