Modern applications rarely work in isolation — they need to exchange data with other systems securely, reliably, and at scale, and Java remains one of the most widely used technologies for building that layer. This training course from the Arab British Fellowship Training Academy gives participants hands-on practice building, deploying, and monitoring both SOAP and RESTful web services in Java, rather than only covering the theory behind them.

Working through practical exercises, delegates learn to create secure, scalable, and maintainable web service solutions, covering SOAP and REST as the core web-based technologies alongside JSON and XML for data transfer. By the end of the course, participants have a working, end-to-end understanding of the Java web services landscape.

Who should attend?

• Programmers, designers, and architects who need to build and understand web services in a Java environment.
• Testers and anyone who needs a solid working understanding of Java web services solutions.

How attendees will benefit?

After completion of the course, delegates will understand:

• Building contract-first web services from WSDL as well as code-first web services, and modifying and deploying a service’s WSDL.
• Building, deploying, and monitoring both SOAP and RESTful web services, and creating REST web services from scratch.
• Generating XML using JAXB and transferring data using JSON.
• Building secure SOAP and REST clients.

Module 1: Course Orientation and the Role of SOA

• Management and course materials, course structure and agenda, and presentation of delegates and coaches.
• SOA architecture design and implementing SOA using web services.
• Web services overview and the Java API for web services.

Module 2: XML Foundations for Web Services

• XML schema, XML namespaces, XPath, and XSLT.
• Java APIs for XML parsing and transformation: SAX, DOM, and StAX.

Module 3: SOAP Web Services from Design to Client

• Introducing SOAP, SOAP message structure, and WSDL.
• Defining web service interfaces with SoapUI and SAAJ.
• Building web services using JAX-WS: POJO annotations, and configuring and deploying web services.
• Implementing a Java SOAP client: generating client artifacts from WSDL, message monitoring, and client authentication and authorization.

Module 4: Data Binding with JAXB

• Mapping XML with JAXB.
• Transforming Java arguments with JAXB and JAX-RS.

Module 5: RESTful Services and the JAX-RS Alternative

• REST architectural style and comparing SOAP and RESTful web services.
• Adding JAX-RS annotations to a POJO, working with request URLs, and mapping URLs to Java classes and methods.
• Using HTTP request headers, providing a JAX-WS service, and binding URL components to method arguments.

Module 6: Interoperability, JSON and AJAX Clients

• Web Services Interoperability Technologies (WSIT): overview, binary attachment scheme (MTOM/XOP), and WS-Reliable Messaging.
• Processing JSON, JSON with RESTful services, interpreting a JSON message, JSON generation with JAXB annotations, and JSON return types from Java methods.

Module 7: Securing Web Services

• WSIT security and web services security with Jersey.
• HTTP basic authentication and secure messaging with SSL/TLS.
• Client authentication and authorisation.
