Developing Flex Applications that Invoke SAP Services

You can now develop your favorite Flex based client application that consumes SAP services. SAP has provided an Eclipse plug-in that generates ActionScript proxy classes for the invocation of a Web service represented by a WSDL file.  This plug-in will generate classes that represent data types, operations, ports and services as defined in the WSDL file. The Eclipse plug-in can be deployed into Adobe Flex Builder, SAP NetWeaver Developer Studio, or any other Eclipse-based IDE.

To get started, download the plug in by clicking here and then download the documentation, which is available as two separate documents. The first document, called “Connecting SAP Enterprise Services with Flex Controls” gives an in-depth overview of the technology. The second document, titles “How to Develop Flex Applications that Invoke Web Services“, is a how-to guide to help you in step by step fashion to build your first application. please note that this plug in is provided as is, on a trial basis only.

The basic features of the plug-in are summarized below:

Feature Flex Out of the Box With SAP Plugin
Web service method calls x x
Action Script proxy generation   x
Support for simple WS structures   x
Support for complex WS structures   x
Flex UI generation based on WS definition   x
SAP NetWeaver Eclipse based IDE integration   x
Javadoc-like generated documentation for the generated proxy classes   x

This Eclipse plug-in will also allow you to generate MXML screens (i.e. data forms) to represent input arguments and output results for each operation defined by the selected WSDL file. These forms can be used to execute Web service calls right away, without extra coding, and can also be used by the developer as a starting point for further polishing, mending and composing them into a finished application.

The plug-in also generates Javadoc-like documentation for generated classes that represent operations and data types defined by the selected Web service. This documentation is orders of magnitude more convenient to use for a developer than digging into raw WSDL file.

Finally, the plug in also generates a runtime for binding screen elements to data structures. This runtime glues to the generated screens and allows interactive creation and editing of complex nested data structures as well as interactive browsing of such structures without a developer having to write a single line of code for that. Generated screens also include pre-cooked code for the invocation of Web services when the “Execute” button is clicked. Whenever a response from a Web service is received, the pre-cooked code in the screen automatically displays the output screen in the application window and displays received response data within this screen. This code can be overwritten by developers according to specific needs.

  • Hi Axel:

    Pretty cool! Thanks -:) I have already downloaded both the plug-in and the documentation. Can’t wait to start playing with it -:D

    if this is the case why not changing SDN message for a new one adressing us to the author of the blog?

  • Firstly I would like to thank you for the blog and the detailed pdf document. I decided to try installing the flex plugin into SAP developer studio. I used SAP NetWeaver Developer Studio
    SAP NetWeaver 7.1 Composition Environment SP01
    Build id: 200705231918.

    When I reached step 2 in “Getting Started: Creating Your First Project” I got an error. The error was as follows:
    “A problem occurred when opening this project. Try quitting and restarting the application. If this problem persists, you may be using an unsupported project version or your project files may be corrupt”

    After I clode this error the following error is displayed in the problems section:
    “The project properties files could not be read.”



    • Ok, I’ve managed to get passed this error by first creating a ‘Flex Library Project’ named runtime and then only importing the ‘com’ folder with all it’s subfolders. This seems to work. I then carried on but I am now stuck at step 5 – Build actionscript proxies. The errors I get is as follows:

      1120: Access of undefined property SAPLog.     proxies/sap/theme/standard/skin     line 57     1201505011870     23
      1172: Definition sap.chart.graph:GraphChildrenButton could not be found.     proxies/sap/theme/standard/skin     line 5     1201505011870     25
      1172: Definition sap.utils:SAPLog could not be found.     proxies/sap/theme/standard/skin     line 4     1201505011870     24

      As far as I can tell the problem is with the import statements:

      import sap.utils.SAPLog;
      import sap.chart.graph.GraphChildrenButton;

      There are no subdirectories sap.utils or sap.chart?

      Please assist…



  • Hallo,

    works the Add-in only for RFC´s or also for WebServices ;-))
    I tested it for a Web service and received Java error messages.
    The WSDL in the document “Connection SAP Enterprise Services with Flex Controls” is a RFC-WSDL and not a WebService-WSDL.
    Please clear me up, if I wrongly understood it.

  • Hi,

    sorry, but I have to give more information:
    The SAP Add-in works also for WebService and RFC´s.
    But we have upgraded to SAP_ABA     to SP14, SAP_BASIS to SP14 and SAP_BW to SP16. After that, the new generated WebServices are not working with the SAP Add-in.
    I can use the Add-in for a RFC, but not a WebService of the function module.
    I hope, this helps to solve my problem
    Thanks a lot

  • I have installed the actionscript proxygen plugin in both a vanilla Eclipse environment and a NetWeaver Composer environment.  Unfortunately, I’m unsure how to invoke the plug-in — I couldn’t figure out how to do it from the docs.  Any assistance getting started would be most appreciated.  Thank you in advance.
    • Please disregard my first post.  I did not realize there was a second step-by-step document that explained how to use the plug-in.  I’ve downloaded the document now and will attempt to set up the HTTP proxy server as described in it.  If I still run into problems, I will post back here.  Thanks.
  • Hi,

    Would it be possible to get the source code?
    Which license would apply?

    I have seen several WSDL to ActionScript Proxy generator on the Web
    – first of all, Flex Builder 3 is able to do it 😉
    – FleXtense 2.0
    – WebOrb
    but none provides MXML default screen generation as you do…

    That is why I would like to know if there is any way to find out how this can be done.

    Thanks in advance for your answer.

    Best regards,
