Implementing and Exposing a Web Dynpro as a Callable Object

Purpose

In this tutorial you learn how to provide a Web Dynpro application that can be used to complete a simple task within a business process modeled with Guided Procedures.

You do this by creating a local Web Dynpro component, which, in our example, should read the following data about an existing system user, whose details are provided in User Management:

• First name
• Last name
• Telephone number
• Fax number

Prerequisites

• You are familiar with the basic principles of Java programming.
• You have an overview of Web Dynpro programming.

Process Flow

To implement a Web Dynpro callable object, you must:

1. Create and configure the Web Dynpro project
2. Implement the GP interface for Web Dynpro callable objects
3. Deploy the Web Dynpro application
4. Expose it as a callable object in the GP design time
5. Test and activate it.

You start with Creating and Configuring the Web Dynpro Project .
