Enterprise JavaBeans (EJB) is a specification for developing scalable, server-side, multi-user enterprise applications. When you test components like EJBs or other remote components, you cannot use HTTP traffic when the application expects RMI or RMI over IIOP traffic. To communicate with the application, Silk Performer must invoke a Java client that generates the appropriate protocols that can be used to approach the interface of the application.
Java Remote Method Invocation (RMI) technology is developed jointly by Sun Microsystems and IBM. RMI delivers CORBA-distributed computing functionality to the Java 2 platform, when the technology is run over Internet Inter-Orb Protocol (RMI-IIOP).
