Hi friends,
I am developing an application in EP6 SP2 using JSPDynPage from which, want to call an ABAP function module that returns table and show the values from this table in this application.
I went thru various blogs and APIs. I am confused between SAP JCO, JCO client service and connector framework. Do u have any documentation on how to connect to R3 systems and call a function module, retrieve results etc.
Regards,
Nilz
JCo is the point to start. This gives you low level access to all rfc functions. Everything else (accept BSP and Web dynpro) are just layers of encapsulation around the low level JCo function.
The steps are always like this:
call the sap system for rfc login
prepare data areas and call in java
call the rfc in the R/3 system
handle exceptions
logoff and free ressource
continue with data obtained in R/3
There is a lot of material around jco. One book that is fairly ok is :
SAP Interface Programming
A comprehensive reference for RFC, BAPI, and JCo programming
J. Meiners, W. Nüßer
SAP PRESS ISBN 1-59229-034-5
This helps you navigate through the wealth of information also at SDN

Hi Nilz,
if you have a Backend System > 6.20 you can also add Web Service to the list of possible connectors. I think first you should try the easy way via JCo.
