SAP Java Connector (SAP JCo)
The SAP Java Connector (SAP JCo) is a middleware component that enables Java applications to communicate with SAP systems using Remote Function Calls (RFC). Developers use it to invoke ABAP function modules from Java code, supporting both inbound and outbound RFC-based integrations. On SAP Business Technology Platform, SAP JCo is available to developers through the SAP Java Buildpack.
