How is SAP JCo different from SAP .NET Connector?
SAP .NET Connector is based on Microsoft .NET. The SAP .NET Connector offers developers the possibility to expose BAPIs and remotely enabled function modules to any .NET application (inside-out). It is also possible to access .NET components from a SAP System (outside-in). SAP JCo employs standards based information exchange between SAP and a Java application. Additionally, SAP JCo together with the SAP Java IDoc Class Library offer high level support for IDocs.
