Class Description

Class Overview

Class Goals

• Be able to describe the interoperable web services architecture, including the roles of SOAP and WSDL.
• Understand the importance of the WS-I Basic Profile for interoperable web services.
• Build JAX-WS services and clients that take full advantage of the automated data binding of JAXB.
• Use lower-level SOAP and XML APIs for services and/or clients.
• Customize data binding by specifying specific type mappings or altering method or parameter names.
• Expose session beans as web services.
• Incorporate binary data, such as images, into service and client code.
