Java Web Services

Complete Java Web Services

The Complete Java Web Services class teaches students how to build Web Services and Web Service clients using Java Technologies. The class includes a high-speed introduction to XML syntax, namespaces, XML Schema, SOAP, and WSDL before exploring Web service client or server-side development in Java APIs and tools. The course focuses on implementation using Apache Axis, the most popular Java JAX-RPC implementation.

nTier’s Developing Java Web Services training class prepares Java programmers to develop interoperable Java Web services and using SOAP, WSDL, and XML Schema. Students get an overview of the interoperable and Java-specific Web services architectures, and then learn the standard APIs for SOAP messaging and WSDL-driven, component-based service development. Both document-style and RPC-style messages and services are covered in depth.

The introductory chapters give overviews of the consensus architecture for interoperable Web services, including the WS-I Basic Profile, and the Java Web services architecture as codified by the J2EE 1.4 specification, including SAAJ and JAX-RPC. These chapters are meant to be equally useful to developers and non-developers �project managers, analysts, technologists and support staff.

There is a great deal of hands-on demonstration of running Web services, inspecting SOAP traffic, WSDL definitions, and a little bit of Java code, but no Java coding. The focus is on the architecture itself, and on the roles that various protocols, APIs, tools, and application components play in a working Web service and/or client. The course then gets down to the various brass tacks: students learn the Simple Object Access Protocol (SOAP) 1.1, and acquire skills in using the SOAP with Attachments API for Java (SAAJ) and the Java API for XML Messaging (JAXM) to build "low-level" SOAP- based Web services and clients, in which the programmer is responsible for element-by- element content of the SOAP message. Students will learn to read SOAP and to write it by hand, and then will proceed to use the Java APIs to develop servlets that respond to SOAP/HTTP messages.

The course then moves to "high-level" services: component-based development using the Web Services Description Language (WSDL) to define interoperable messaging models and the Java API for XML-Based RPC (JAX-RPC) to automate the SOAP messaging for remote procedure calls between objects. JAX-RPC abstracts almost all the transport-level implementation �SOAP over HTTP �and this allows the Java developer to concentrate on application and service specifics. (In this way JAX-RPC is analogous to Java RMI and the EJB architecture: SOAP/HTTP is treated as nothing more or less than an RPC transport protocol.)

Students get hands-on experience in developing Web services starting either from WSDL descriptors or from existing J2EE applications. Both servlet and EJB endpoint models are studied, as is the management of SOAP headers using JAX-RPC handler chains. Finally, the course covers advanced techniques including SOAP attachments (using either SAAJ or JAX-RPC), EJBs and JSPs as Web services and clients, and Java Web-service security.
