RMI-IIOP using JAX-RPC

Java API for XML-based Remote Procedure Call (JAX-RPC) is the Java standard API for invoking Web services through remote procedure calls. A transport is used by a programming language to communicate over the Internet. You can use protocols with the transport such as SOAP and Remote Method Invocation (RMI). You can use Remote Method Invocation over Internet Inter-ORB Protocol (RMI-IIOP) with JAX-RPC to support non-SOAP bindings.

Using RMI-IIOP with JAX-RPC, enables WebSphere Java clients to invoke enterprise beans using a WSDL file and the JAX-RPC programming model instead of using the standard J2EE programming model. When a enterprise JavaBeans implementation is used to invoke a Web service, multiprotocol JAX-RPC permits the Web service invocation path to be optimized for WebSphere Java clients. Learn more about this by reviewing Using enterprise bean bindings to invoke an EJB from a Web services client. Benefits of using the RMI/IIOP protocol instead of a SOAP- based protocol are:

• XML processing is not required to send and receive messages; Java serialization is used instead.

• The client JAX-RPC call can participate in a user transaction, which is not the case when SOAP is used.
