A Web Service is a distributed application or business logic process that is accessed using standard Internet protocols. Web Services combine the best aspects of component-based development and the WWW.
Like components, Web Services give "black-box" functionality that can be used and reused without regard to how the service is implemented.
The course provides an overview introducing the use of Java Web Services. The course introduces delegates to the latest strategic and practical issues in using Java APIs for developing Web Services

Sign up for the JBI Training newsletter to stay updated with world-class technology training opportunities, including Analytics, AI, ML, DevOps, Web, Backend and Security. Our Power BI Training Course is especially popular. Gain new skills, useful tips, and validate your expertise with an industry-leading organisation, all tailored to your schedule and learning preferences.
Client feedback shows that delegates on our courses will best engage when they can relate course topics to their own day-to-day practices and requirements. Where possible, we run this course as a consultative, workshop-style event, in which discussion of relevant topics takes place in relation to the delegates' own applications and scenarios.
To facilitate this type of event, a subject matter expert leads the training, hands-on labs and discussions to ensure course topics are covered in a meaningful, relevant and timely manner. Delegates may be able to bring their own practical requirements and work to the course if the subjects and course topics are suitable.
