In this article I give a short overview of the important JSR of Java Community Process which defines and standardizes WebServices development with Java Platform.
-
JSR-175 : A Metadata Facility for the Java Programming Language. Also known as Java Annotations e.g. @Deprecated or @Override.
-
JSR-181 : Web Services Metadatata for the Java Platform. This is just a set of Annotations for using with JAX-WS WebServiceces. Think of Annotations @WebService, @WebMethod…
-
JSR-101 : API for XML-based RPC: JAX-RPC 1.1. Definition of RCP call with SOAP Messages, Type Mapping between Java and XML.
-
JSR-109 : Implementing Enterprise Web Services Definition of Web Services based on JAX-RPC which is now accessed by JAX-WS. That early standard defined Web Services for J2EE 1.4. It enabled implementation of Web Services as Endpoints over Enterprise Session Bean’s (EJB 2 generation with awful XML descriptors).
