	The '''Java Remote Method Invocation''' ('''Java RMI''') is a [[Java (programming language)\|Java]] [[~~Application programming interface\|~~API]] that performs [[remote method invocation]], the object-oriented equivalent of [[remote procedure call]]s (RPC), with support for direct transfer of [[Serialization#Java\|serialized]] Java classes and [[Distributed Garbage Collection\|distributed garbage-collection]].		The '''Java Remote Method Invocation''' ('''Java RMI''') is a [[Java (programming language)\|Java]] [[API]] that performs [[remote method invocation]], the object-oriented equivalent of [[remote procedure call]]s (RPC), with support for direct transfer of [[Serialization#Java\|serialized]] Java classes and [[Distributed Garbage Collection\|distributed garbage-collection]].

	The original implementation depends on [[~~Java virtual machine\|~~Java Virtual Machine]] (JVM) class-representation mechanisms and it thus only supports making calls from one JVM to another. The protocol underlying this Java-only implementation is known as Java Remote Method Protocol (JRMP). In order to support code running in a non-JVM context, programmers later developed a [[Common Object Request Broker Architecture\|CORBA]] version.

	Usage of the term '''RMI''' may denote solely the programming interface or may signify both the API and JRMP, [[IIOP]], or another implementation, whereas the term [[RMI-IIOP]] (read: RMI over [[IIOP]]) specifically denotes the RMI interface delegating most of the functionality to the supporting [[CORBA]] implementation.

	==Generalized code==		==Generalized code==
	The programmers of the original RMI API generalized the code somewhat to support different implementations, such as a [[~~Hypertext Transfer Protocol\|~~HTTP]] transport. Additionally, the ability to pass arguments "[[Call by value\|by value]]" was added to CORBA in order to be compatible with the RMI interface. Still, the RMI-IIOP and JRMP implementations do not have fully identical interfaces.

Still, the RMI-IIOP and JRMP implementations do not have fully identical interfaces.

	RMI functionality comes in the package {{Javadoc:SE\|package=java.rmi\|java/rmi\|module=java.rmi}}, while most of Sun's implementation is located in the <code>sun.rmi</code> package. Note that with Java versions before Java 5.0 developers had to compile RMI stubs in a separate compilation step using <code>'''rmic'''</code>. Version 5.0 of Java and beyond no longer require this step.

	Usage of the term '''RMI''' may denote solely the programming interface or may signify both the API and JRMP, [[IIOP]], or another implementation, whereas the term [[RMI-IIOP]] (read: RMI over [[IIOP]]) specifically denotes the RMI interface delegating most of the functionality to the supporting [[CORBA]] implementation.
