Java Training : Fast Track to SOA, Java® Web Services (JAX-WS) and JAX-RS (REST)

Fast Track to SOA, Java® Web Services (JAX-WS) and JAX-RS (REST)

Java Training Overview

Web services are designed to allow Web-based access to distributed software and business services. They bring a standard, open service architecture to component development that allows them to be accessed over the Web with standard protocols such as HTTP and standard XML formats for messages and service descriptions. This course will give you a thorough understanding of the current Web services architecture, and the technologies that support Web services including the new Java APIs such as JAX-WS and JSR-181. Topics include:

SOAP - An XML based messaging mechanism.
WSDL - Web services Description Language – An XML language that describes the interface and semantics of a Web service.
JAX-WS – Accessing Web services using the latest Java APIs including JAX-WS, JSR-181, JAXB
SAAJ – Soap with Attachments API for Java
Soap Handlers
JAXB - Java Architecture for XML Binding
XML Web Services - Working with Web services directly at the XML level
MTOM - Handling binary message data in an interoperable way
Security – Basic Authentication, HTTPS, and Web Services Security (WS-Security)
EJB based Web Services
The WS-* Standards – A Brief Overview
Building REST-based Services with JAX-RS

We will look at the current state of the art of Web services, what works and what doesn’t work, and also at newer standards, and how they fit into the Web services picture. This course is hands on, and students will actually build and deploy Web services during the course.
