RMI is the standard model for distributed object programming in Java. Using RMI, a Java client can access a remote object seamlessly on another JVM, and invoke methods on the object as if it were located within the client’s JVM. In addition, RMI incorporates various reference semantics for remote objects, such as lazy activation, live (or nonpersistent) references, and persistent references.

WebLogic RMI is an integral part of the server framework. It enables a Java client to transparently access RMI objects that live on WebLogic Server. This includes access to any EJB components and other J2EE resources that have been deployed to WebLogic. It allows you to build fast, reliable, standards-compliant RMI applications. It also incorporates support for load balancing and failover when RMI objects are deployed to a WebLogic cluster. WebLogic RMI is fully compatible with the RMI specification, but provides extensions not available under the standard RMI implementation. Here’s a brief overview of some of the extra benefits of using WebLogic’s version of RMI.

Performance and scalability

WebLogic incorporates a highly optimized implementation of RMI. It handles all the implementation issues that relate to the support for RMI: managing threads and sockets, garbage collection, and serialization. Standard RMI relies on separate socket connections between the client and the server, and between the client and the RMI Registry. WebLogic RMI multiplexes all this network traffic ...
