Extract R/3 data via EJB

Posted on Feb 09, 2005 at 09:08 AM 19 Views

Hi *,

I'm looking for a best way in order to extract data form an ABAP (R/3) system and exspose those data via a Web Service. The scenario I thought, is to use a WAS 6.40 and implement an EJB which get necessary data via a BAPI call (using JCo or JCA) and build, upon this EJB, a web service (using developer studio wizard).

So my questions are:

1) what do think about this kind of scenario? Do you know any better ways to achive the same objective?

2) Do you know if there're any documentations or whatever which could help me in order to develop an EJB which collect data from an ABAP (R/3) system?

Any hints will be very precious

Many thanks

Cheers

Roberto

    Hi Roberto,

    the best way to achieve this depends on the version of the ABAP system. If the version is >= 6.20, you can create the Web Service directly in the ABAP system and there's no need to use the Java personality of the WebAS and EJBs to achieve this. You may have a look at <a href="/people/thomas.jung3/blog/2005/01/05/develop-a-web-service-that-sends-an-email--in-abap Jung's weblog entry</a> describing how to create a Web service using ABAP. There are some 6.40 specific features used, but anyway.

    Hope that helps.

    Regards

    Stefan
