Course Description:

Fast Track to Web Services and Java

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. Web services are still evolving rapidly, and this course will give you a thorough understanding of the current Web services architecture, and the technologies that support Web services including:

SOAP – Simple Object Access Protocol - A remote invocation (RPC) and messaging mechanism.
WSDL – Web services Description Language – An XML language that describes the interface and semantics of a Web service.
UDDI – Universal Description, Discovery, and Integration – A standard for describing, publishing and finding Web services.
JSR101/JAX-RPC – Accessing Web services using Java
SAAJ – Soap with Attachments API for Java
WS Security – Web Services Security
WS-I –Web Services Interoperability
JSR109 – Creating Web services with J2EE/EJB

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.
