Security Guide for Connectivity with the AS Java

Java Remote Method Invocation (RMI) enables the creation of Java-to-Java applications between remote Java Virtual Machines (JVMs).  An example of the use of RMI is the communication between external Java applications and the SAP NetWeaver AS.

You can use RMI either using the P4 protocol, which is an SAP-proprietary protocol, or the Internet Inter-ORB Protocol (IIOP).

The security aspects involved when using RMI are described in the following topics:

• Authentication for RMI-P4 Clients
• Using P4 Protocol Over a Secure Connection
• Security for RMI-IIOP Applications
• Configuring the AS Java for IIOP Security
