View source for Jakarta XML RPC

{{Short description|Jakarta EE specification}}
'''Jakarta XML RPC''' ('''JAX-RPC'''; formerly Java API for XML Based RPC) allows a [[Jakarta EE]] application to invoke a Java-based [[web service]] with a known description while still being consistent with its [[Web Services Description Language|WSDL]] description. JAX-RPC is one of the [[Java XML]] programming APIs. It can be seen as [[Java remote method invocation|Java RMI]]s over web services. JAX-RPC 2.0 was renamed JAX-WS 2.0 ([[Java API for XML Web Services]]). JAX-RPC 1 is deprecated with Java EE 6.<ref>[https://stackoverflow.com/questions/3307516/jax-ws-vs-jax-rpc/3314458#3314458 JAX-WS vs. JAX-RPC - stackoverflow.com]</ref> The JAX-RPC service utilizes W3C (World Wide Web Consortium) standards like WSDL (Web Service Description Language).<ref>[http://www.qwhatis.com/what-is-jax-rpc/ What is JAX-RPC - qwhatis.com]</ref>
The core API classes are located in the [[Java package]] {{Javadoc:EE|package=javax.xml.rpc|javax/xml/rpc}}.
* Supports web-based services and clients using [[Remote procedure call|RPC]] or remote procedure calls which are based on [[XML]].
* Allow for web service accessibility through Java APIs which in turn allows for communication between different Java applications.
* Enables client communication with web service of different language and running on separate platform.

It works as follows:
#A Java program executes a [[method (computer science)|method]] on a [[method stub|stub]] (local object representing the remote service)
#The stub executes routines in the JAX-RPC Runtime System (RS)
#The RS converts the remote method invocation into a [[SOAP (protocol)|SOAP]] message
#The RS transmits the message as an [[HTTP]] request

The advantage of such a method is that it allows the Web service to be implemented at server-side as a [[Jakarta Servlet|Servlet]] or [[Jakarta Enterprise Beans|EJB]] container. Thus, Servlet or EJB applications are made available through Web services.

Jakarta XML RPC (JAX-RPC) was removed from Jakarta EE 9.<ref>{{cite news |last1=Kaltepoth |first1=Christian |date=2020-01-17 |df=mdy |title=A deep dive into the Jakarta EE 9 Release Plan |work=JAXenter |publisher=Software & Support Media |url=https://jaxenter.com/jakarta-ee-9-release-plan-deep-dive-166910.html |access-date=2020-12-05}}</ref>
