Jakarta XML RPC
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 WSDL description. JAX-RPC is one of the Java XML programming APIs. It can be seen as Java RMIs 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.[1] The JAX-RPC service utilizes W3C (World Wide Web Consortium) standards like WSDL (Web Service Description Language).[2]
The core API classes are located in the Java package javax.xml.rpc.
- Supports web-based services and clients using 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 on a 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 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 Servlet or EJB container. Thus, Servlet or EJB applications are made available through Web services.
Jakarta XML RPC (JAX-RPC) was removed from Jakarta EE 9.[3]
