Hi Krishna,

The <b>SAP Java Connector (SAP JCo)</b> is a toolkit that allows a Java application to communicate with any SAP System.

SAP JCo can be used for communication between SAP and any Java application via RFCs, BAPIs, and IDocs.

SAP JCo appears to an SAP System as an RFC Destination. To direct a BAPI or IDoc Call to SAP JCo you just use this <b>destination</b>. To incorporate external data or services into your SAP System you create a Java Application, which defines the interface to the data, and call the implementation.

The portal system landscape is a collection of systems. A system is a portal object comprised of a set of properties that represent an external, or back-end, application. Systems enable a connection to these applications and the retrieval of data from their information stores.

In the PCD, the portal stores systems, which are sets of properties that represent an external back-end application. Systems, such as for JDBC-compliant databases or SAP R/3 systems, enable connections to specific applications of these types and the retrieval of data.
