by Chris Whealy, RIG Expert (Web Dynpro), SAP NetWeaver Regional Implementation Group (RIG) EMEA, Walldorf, Germany
When used correctly, Web Dynpro is an efficient and powerful tool for building robust and reliable business applications. Web Dynpro is unlike other Web development toolsets, however, and if developers use it incorrectly, they will create poor-quality applications that are difficult and costly to maintain. This article describes the most common mistakes made in Web Dynpro Java implementations, why they occur, and how to avoid them. It then explains the key design principles that will enable you to write high-quality, low-TCO business applications and start reaping the real rewards of Web Dynpro.
- Integrate Web Dynpro into your SAP NetWeaver Portal to create dynamic, flexible applications
by Jochen Guertler
Combining Web Dynpro (to create state-of-the-art, Web-based business applications) and SAP NetWeaver Portal (to securely deliver applications to users) can provide more robust results than simply creating an iView in the portal to display the application. Instead, you can build professional portal systems that provide users with the best of both technologies: appealing, secure, and dynamic applications that you can quickly customize. Using an example, this article demonstrates how a tight coupling of Web Dynpro and SAP NetWeaver Portal allows you to create sophisticated, state-of-the-art portal applications.

- Streamline business processes and increase user productivity with SAP
NetWeaver: Build forms-based Web Dynpro applications using Interactive Forms
based on Adobe software
by Markus Meisl and Marc Chan
Until now, users have required direct access to the back-end system to carry out daily business tasks, such as entering sales order information, which can be problematic for remote or offsite users. SAP NetWeaver ’04 offers a new technology called Interactive Forms based on Adobe software that changes all this. Leveraging the presentation and information exchange capabilities of Adobe’s Portable Document Format (PDF), Interactive Forms enables users to take parts of their business processes offline by entering data into form fields and then uploading the data in the fields to the back-end system, increasing efficiency and reducing the risk of data entry errors. Using an example, this article show developers how to build and deploy a custom data-entry form using Interactive Forms within a Web Dynpro application.
