- Build Multiple Web Service-Consuming Flex Applications Using Proxy Classes
by Sandesh Darne, Consulting ERP Practice at L&T Infotech (October 2009)
Proxy classes for use in Web applications can be automatically generated by ActionScript, an SAP NetWeaver plug-in, integrated with Adobe Flex Builder 2 or via a wizard in Adobe Flex Builder 3. How the proxy classes are created isn’t as important as your understanding the proxy class structure. Learn how to deal with generated proxy classes to develop code in Flex applications that consume enterprise services.
- Capture accurate solution requirements the first time with exploratory modeling (xM): How to
nearly eliminate post-go-
live application design failures
by Heinz Roggenkemper, Executive Vice President of Development, SAP Labs
Ralf Ehret, Development Architect, SAP AG
Andreas Tönne, Lead Consultant, Cincom Systems
The lack of a common language between business users and developers during application development projects often results in developers spending a lot of time designing a solution that does not meet user needs. This article explores an approach to application development called exploratory modeling (xM) that reduces the risk of application design failure by using non-technical, business-level tools and concepts to create an application model, and then enabling fine-tuning of the model through shortened, interactive analysis and design cycles. The article starts by examining the root causes of design failures, and then defines the xM approach and discusses how it was successfully used in two projects.

- Extend the Internal and External Reach of Your Applications with ABAP-Based Web
Services
by Arthur Wirthensohn, Senior Consultant, EDS Switzerland
Web services technology enables application-to-application communication using Internet standards (i.e., XML) to gain high interoperability and software- and platform-independence while ensuring smooth-running, reliable distributed business processes. Previously, you could only enable SAP applications for Web services using specialized integration tools such as the SAP Business Connector. Starting with Release 6.20, however, SAP Web Application Server (SAP Web AS) includes built-in support for implementing and running Web service applications. This article takes you on a tour of the capabilities for Web service development in the ABAP-based SAP Web AS 6.20 and 6.40 and walks you through some hands-on examples that you can duplicate in your own environment.

- Quickly and Easily Map Your ABAP and XML Data Using SAP Simple Transformations
by Karsten Bohlmann, Developer, ABAP Language Group, SAP AG
XML is at the heart of a number of developments that are likely to become basic technology standards, such as Web services. In turn, the ability to move data between XML documents and your ABAP data structures is becoming a key business requirement. While middleware like the SAP Exchange Infrastructure supports this task for large-scale system integration projects, SAP also provides mapping technology directly to ABAP developers for smaller-scale development tasks. This article introduces Simple Transformations, a special-purpose language included in the 6.40 ABAP kernel that enables high-performance ABAP-XML mappings. It outlines the fundamental concepts of the language, and provides a detailed tour of its key constructs.
- Unveil the power of loosely coupled composite applications by replacing services for additional functionality
by Volker Stiehl, Product Manager, SAP AG
One of the key benefits of composite applications is its flexibility, the capability to replace services to accommodate different functional needs. Whether you are upgrading to the newest SAP release, adding new business logic, or integrating new back-end systems — a common requirement in mergers and acquisitions — composite applications
enable you to “plug ‘n’ play” different functional implementations by using a common interface. The replacement technique shows you how to replace services without affecting their consumers. Learn how it can help you face the challenges of changing business or IT requirements. Once you have used it, you’ll never let it go.
