SAP JCo Scenario: Java/ABAP Communication in the SAP Application Server 

 

In the SAP NW Application Server (SAP_BASIS), you can work both in a Java environment and in an ABAP environment. Communication between these components is established by the SAP JCo. Figure 1 shows an overview of the architecture of the SAP Application Server with the SAP Java Connector as the interface between the Java and the ABAP environment:

Data transfer between SAP JCo and the ABAP environment is performed by means of RFC (with gateway communication by means of CPI-C):
