After profiling the resource, identify classes and methods needed in your adapter:
Review the relevant Javadoc to determine which base classes and methods you can use as is and which you must extend. This javadoc is available on your Identity Manager CD in the REF/javadoc directory.
Create a list of methods that you must write and include in the Java file based on the resource to which you are connecting.
When creating an adapter, the most time-intensive task is writing your own methods to push information from Identity Manager to the resource or to create a feed from the resource to Identity Manager.
