Extract R/3 data via EJB
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
