SAP is such one of the most complex ERP on earth. It is designed for extensibility and scalability, especially in cluster environment. As a result, most services are accessible via internet protocol aka TCP/IP. So, you have to know IP address and port for such a service, e.g. J2EE. This is a bit funny. SAP uses wide range of TCP/IP ports.

If you have to work with recent version of SAP, don't forget to obtain TCP/IP Ports Used by SAP Applications as a must-have reference on your desktop.
