Developing SOAP Web-Services in JAVA

Prerequisites

• Strong Java programming skills are essential.
• Students must be able to read XML documents and to write well-formed XML by hand
• Knowledge of XML Schema will be helpful, too, but is not a strict prerequisite.
• Experience with other Java EE standards, especially servlets and JSP, will be very helpful in class, but is not strictly required.

Learning Objectives

• Be able to describe the interoperable web services architecture, including the roles of SOAP and WSDL in component-based services and XML and HTTP in the REST architecture.
• 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.
• Build WSDL-to-Java and Java-to-WSDL services, with equal facility.
• Apply advanced techniques and best practices including proper exception handling, care around possible polymorphism, and use of context and lifecycle services.
• 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.
• Incorporate binary data, such as images, into service and client code.
