JCO RFC provider and JCO connection

[Former Member]

Hi all:

Please share your thoughts on the following doubts I have. Thanks.

1. To my understanding, we use JCO RFC provider(define in Java side) and RFC destination(in SM59) when we have request from ABAP to Java side. Then we use JCO destinations(define in Web Dynpro Content Admin) if we have request from Java to ABAP. Is this correct?

2. When creating the JCO RFC provider service, why we need to create those entries for repository for example, the server name, the user used to log into repository? What is the repository used for?

Thanks!

Hai,

your understanding of JCO RFC and RFC Destination is right.But JCO Destination gets the metadata and model data from ABAP,thats what we mention the Dictionany meta data and Application data while creating them.

Yes, we need to mention the application host,sys no,client and userdetails while creating the JCO RFC provider,then only it will fetch the data from that host and that particular client.

Thanks and Regards,
