Hi,

Another option is to expose your Java program as a web service. Then, do a standard web service call from your ABAP system, assuming you ar en AS ABAP 6.40 or later.

Here are instructions for SAP NetWever 2004

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.

Implement an RFC server in 7.0:

Implement an RFC server in 7.1 or higher:

Hi,

You can use EJB on Java Side and call it using JCo RFC Provider Service
