JAX-RPC step 1.step 1 brings interoperability that have Online characteristics in accordance with the WSDL and Soap standards. The fresh J2EE step one.cuatro system along with helps the web based Properties getting J2EE specification (JSR 921), and this talks of implementation standards having Net qualities and you will makes use of the newest JAX-RPC programming model. Including several Websites attributes APIs, J2EE step one.cuatro platform also features service to your WS-We Basic Character step 1.0.
