The following Guided Answers Decision Tree will help you to resolve problems that you encounter with the below SAP NetWeaver AS Java implementations:

  • RMI - The 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. RMI can be used either using the P4 protocol or the Internet Inter-ORB Protocol (IIOP).

The CROSS service provides the implementation which connects the servers and the ICM through the FCA
