Installing the SAP Java Connector (SAP JCo) 3.x

In this section:

The SAP Java Connector (SAP JCo) is a component provided by SAP ERP that enables the development of SAP ERP-compatible components and applications in Java. SAP JCo is required by the iWay Application Adapter for SAP ERP to support communication with the SAP ERP Server in both directions: inbound calls (Java calls ABAP) and outbound calls (ABAP calls Java). This section describes how to install SAP JCo.

The official supported platform for the iWay Application Adapter for SAP ERP is SAP JCo Version 3.nn for Java Version 1.Rnn. In this section, R refers to the major Java version (5,6, or 7) and nn refers to the minor releases. For a list of supported platforms and exact library names, refer to SAP Note 1077727.

The SAP JCo library files must be downloaded from the SAP Service Marketplace. A valid SAP support ID is required to access the SAP Service Marketplace. For assistance, contact your SAP ERP administrator.

Follow the SAP instructions on how to extract the SAP JCo from the delivery archive.
