What is actually difference between J2EE 1.step 3 and you will J2EE 1.4? J2EE 1.4 was an improvement variety of J2EE step 1.step 3. It will be the most complete Internet features program ever. J2EE step one.4 is sold with: o Coffee API for XML-Based RPC (JAX-RPC step 1.1) o Soap which have Parts API for Coffees (SAAJ), o Net Qualities to own J2EE(JSR 921) o J2EE Government Model(step one.0) o J2EE Implementation API(step 1.1) o Java Government Extensions (JMX), o Coffees Authorization Bargain to possess Containers(JavaACC) o Java API to possess XML Registries (JAXR) o Servlet dos.cuatro o JSP dos.0 o EJB 2.1 o JMS step one.step one o J2EE Connector step one.5 4 keeps done Online characteristics help from the latest JAX-RPC 1.step 1 API, and this supporting solution endpoints predicated on servlets and you may company beans. JAX-RPC step one.step one brings interoperability with Websites properties according to research by the WSDL and Detergent standards. 4 system and supporting the internet Functions to have J2EE requirements (JSR 921), hence defines implementation criteria to possess Internet qualities and you may uses new JAX-RPC coding design. Together with several Internet services APIs, J2EE step one.4 system also features assistance toward WS-I Basic Profile step one.0. Thus plus program versatility and you can done Websites features assistance, J2EE 1.4 also provides platform Web qualities interoperability. cuatro system as well as introduces the newest J2EE Management step 1.0 API, and therefore talks of all the information design to possess J2EE government, such as the basic Administration EJB (MEJB).
