Development Trends

In the SAP Network Blog SAP and Google Wave – Conversation Augmentation – DJ Adams describes how he has implemented a small demo which will integrate a Google Wave application with SAP Netweaver.

Want to know more about Google Wave – see the following screencast:

Would you like to add some social network functionality to your blog? And maybe share some of the vistitors between related blogs? Then FriendConnect from Google might be a good starting point. It’s easy to implement on your blog without a lot of changes, and there are a lot of different plugin’s available already.

How do I get started with Google FriendConnect?

First you will need to register – and then follow four simple  steps in order to add social network functionality to your blog. I have added the Social Bar plugin at Development Trends – and with this plugin you don’t have to change any pages – just upload the plugin files to your website and you are up and running. And if you want to share visitors with Development Trends – just join by clicking the Social Bar at the bottom of the screen…

For quite some time now SAP and Adobe has presented different methods and initiatives you could use if you would like to integrate Adobe Flex and SAP Netweaver.  I will try to summarize four different scenarios you could consider.

Using SAP Flash Island scenario

If you are using Netweaver 7.0 EhP1 or 7.1 then you can use the SAP Flash Island framework to integrate Adobe Flex with SAP (read more about SAP Flash Island here). The framework will create a ‘bridge’ between a SAP WebDynpro application and Flex. In order to ‘connect to this bridge/framework’ – you need to use a library from SAP in your Flex project – I have created a template project you can use for this purpose click here. Flash Islands are best suited for smaller applications/components – especially for areas where you are missing UI functionality in the WebDynpro, e.g. could be advanced graphics, interactive maps, graphs and statistics. Authentication, User and session management will be handled by the WebDynpro application.

Using SAP BSP and an embedded Adobe Flex component

So what do you do if your application is SAP is not based on WebDynpro – then you will be missing the framework and bridge which will make it easy to communicate with an Adobe Flex application – or ? Well in SAP BSP you can use <object><embed> … </embed><object> to include an SWF application in the application – read more here.  But the data binding and event handling you will have to handle yourself in the BSP and in the Flex application. This kind of integration is also meant for smaller applications/components – especially for areas where you are missing UI functionality in SAP BSP, e.g. again could be advanced graphics, interactive maps, graphs and statistics. Authentication, User and session management will be handled by the SAP BSP application.

Using an HTTP REST backend application in SAP BSP – and an Adobe Flex RIA as Frontend

So… what do we do if we want to build a larger application in Adobe Flex (RIA) which should be integrated with SAP Netweaver? Well.. One possibility would be to build a set of backend services in SAP BSP using the HTTP REST approach/architecture (read more here). In SAP you will then be building normal BSP’s which will receive the input parameters in a HTTP request – and send the reply to the calling application as XML. These services can be called from Adobe Flex using the HTTP-request object. The work could be divided in two parts: the work regarding the design and implementation in SAP and the work with the design and implementation of the RIA using Adobe Flex. In between you need to describe and design the implementation of the interface. User and session management could be handled by the SAP BSP application if it’s running as a state full application. Regarding Authentication you need to consider how you would implement this in the application.

Using WebService enabled SAP BAPI’s as backend application – and an Adobe RIA as Frontend

In the last method you could consider using Webservice enabled BAPI’s instead of having to write BSP’s to communicate with the frontend. From Netweaver 6.40 and onwards all BAPI’s in SAP could be webservice enabled – and from 7.0 the functionality has been improved. And it’s possible to call these webservice enabled BAPI’s directly from Adobe Flex. You can use standard BAPI’s and/or make custom development for your own specific BAPI requests. User and session management should be handled by the Adobe Flex application. Regarding Authentication you need to consider how you would implement this in the application.
