All of the components of the connector can be found in the \connectors\SAP directory.
Prior to installing the connector component of the IBM WebSphere Business Integration Adapter for mySAP.com:
Download the SAPJCo for the operating system on which your connector is running. The SAPJCo is available for download from SAP's website at http://service.sap.com/connectors. You must have an SAPNet account to access the SAPJCo (if you do not already have one, contact your local SAP BASIS administrator).
Add these files to the \connectors\SAP directory after you install the connector. For steps on installing the connector, see Installing SAP's Java Connector (SAPJCo).
SAP delivers Support Packages for: Basis, the R/3 application, ABAP, and HR. They provide bug fixes for the ABAP code in the SAP application. Use an updated SAP kernel. The kernel is the executables, written in C++, that carry out transports, interface with the operating system, communicate with the database, and run the system.
For example, if the connector must perform certain SAP business transactions, the connector's account in the SAP application must have the permissions to perform these transactions. You must set the connector-specific configuration properties ApplicationUserName and ApplicationPassword using this account information. For more information on how to set these properties, see Configuring the connector.
