After you have generated the required support classes for the callback object, you must import them to the SAP NetWeaver Developer Studio. You do this in a newly created project where you will develop all the necessary classes for the client side application.
After completing this step, you have the Client project created and the necessary JAR files added to its classpath. Now you can go on and import the support classes to this project.
You have inserted the necessary classes in the Client project that the client-side application needs to manage the remote calls to the callback object.
With this step completed, you can go on and implement the callback object and the UtilCallback bean's remote client.
