Web Services 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
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 a Web service during the course.
All labs are programmed/deployed with the Eclipse IDE, and the lab instructions include detailed directions for using it.
