Jakarta XML RPC
open-in-new
<p>Jakarta XML RPC (JAX-RPC; formerly Java API for XML Based RPC) allows a <a href="/facts/Jakarta_EE/7AAStd35">Jakarta EE</a> application to invoke a Java-based <a href="/facts/Web_service/qxrwqB3D">web service</a> with a known description while still being consistent with its <a href="/facts/Web_Services_Description_Language/tQPIot4A">WSDL</a> description. JAX-RPC is one of the <a href="/facts/Java_XML/vTpG5fsf">Java XML</a> programming APIs. It can be seen as <a href="/facts/Java_remote_method_invocation/psHXkdWr">Java RMIs</a> over web services. JAX-RPC 2.0 was renamed JAX-WS 2.0 (<a href="/facts/Java_API_for_XML_Web_Services/xcIMaPgp">Java API for XML Web Services</a>). JAX-RPC 1 is deprecated with Java EE 6. The JAX-RPC service utilizes W3C (World Wide Web Consortium) standards like WSDL (Web Service Description Language). The core API classes are located in the <a href="/facts/Java_package/C8PmS7K4">Java package</a> <a href="https://javaee.github.io/javaee-spec/javadocs/javax/xml/rpc/package-summary.html">javax.xml.rpc</a>. </p> <ul><li>Supports web-based services and clients using <a href="/facts/Remote_procedure_call/uMMb9CQw">RPC</a> or remote procedure calls which are based on <a href="/facts/XML/clNgUfWk">XML</a>.</li> <li>Allow for web service accessibility through Java APIs which in turn allows for communication between different Java applications.</li> <li>Enables client communication with web service of different language and running on separate platform.</li></ul> <p>It works as follows: </p> <ol><li>A Java program executes a <a href="/facts/Method_(computer_science)/8kAXxVYs">method</a> on a <a href="/facts/Method_stub/oG08a8Ad">stub</a> (local object representing the remote service)</li> <li>The stub executes routines in the JAX-RPC Runtime System (RS)</li> <li>The RS converts the remote method invocation into a <a href="/facts/SOAP_(protocol)/vXlAMnjp">SOAP</a> message</li> <li>The RS transmits the message as an <a href="/facts/HTTP/TWtvf7JD">HTTP</a> request</li></ol> <p>The advantage of such a method is that it allows the Web service to be implemented at server-side as a <a href="/facts/Jakarta_Servlet/hf5LQVq1">Servlet</a> or <a href="/facts/Jakarta_Enterprise_Beans/3lpxQpDv">EJB</a> container. Thus, Servlet or EJB applications are made available through Web services. </p><p>Jakarta XML RPC (JAX-RPC) was removed from Jakarta EE 9. </p>
